This post refers to this video about a financial dispute about a haircut in China. You can watch it here but it's in Chinese.

Here is what happened.

  • A woman received a haircut, which costs ¥30.
  • The woman realizes she left her money at home. She borrows ¥100 from the barber.
  • The woman pays ¥30 for the haircut and leaves with the other ¥70.
  • Shortly after, the woman returns with ¥100, which she gives to the barber to repay the loan.
  • The barber claims she still owes another ¥30, because she paid for the haircut with "his own money."
  • The woman disagrees and storms out after a fruitless argument about it.


So, who is right? I especially await Nathan's answer.

Joke roundup:

She got a hair cut for 30? Good God, what would he have charged to cut the rest of them?

And that was after she walked in and he told her she needs her hair cut badly. She said "No thanks, you did it badly last time, how about doing it well?"

He couldn't figure this out? No wonder he spent all that time trying to make a dollar out of 15 cents.

Nope, unless you want her to pay twice for the haircut.

This is one of the oldest math riddles that often generates a shitstorm of arguments.

The woman paid for the haircut. She also repaid the full amount borrowed. End.

The two transactions are unrelated.

Do you disagree? Then consider this: Suppose she borrowed the $100 from someone else and paid the barber. She then repaid the $100 to the person she borrowed it from.

It just so happens that it’s not some other person. But that doesn’t change the math.

I'm sure some Americans will claim she actully owes 4.5-6 more for the tip.

It may be useful to think of the till and the wallet.

The till was due ¥30 for services rendered.
The barber's wallet loaned the woman ¥100.
The woman paid the till ¥30.
The woman came back later, and repaid the barber's wallet ¥100.

I do have some respect for the hustle of trying to get paid twice. It's shady, but five bucks is five bucks, and we don't know that he agreed to make the loan for free.
May the cards fall in your favor.

I look it it as debits and credits. From his perspective as a creditor: He gave her a $30 haircut plus a $100 bill. Total value: $130. She gave him $30 in the shop before she left, plus $100 after she came back. Total value: $130. They're settled.

From her perspective as a debtor: She received a $30 haircut plus a $100 bill. Total value: $130. She handed him $30 in the shop and $100 more when she returned. Total value: $130. They're settled.

A couple of truth tables

1)The woman has no money
2) The woman gets a haircut , so she owes $30.
3) The woman borrows $100, putting her total debt at $130.
4) She pays $30, erasing her debt for the haircut. She still owes $100

Axel gets a haircut from Mr Wizard. He owes Mr Wizard $30. He left his wallet at home so he borrowed $100 from his friend Max.
Axel pays Mr. Wizard his $30 and goes home with the $70 he borrowed from Max. The next day he sees Max. Does he owe Max $70 or $100?

I am the barber. I came to work with a $100 bill in my wallet. Mrs. Wizard gets a $30 haircut, so she owes me $30. I lent her $100, so she owes me $130. She pays back $30, so she owes $100.

This is why I hire professionals to do my books.

Why? Because he's bald?

At home in southern Cal I pay nothing because of an arrangement I have with the girl, in Vegas it costs me the tip rest is comp'ed. Both stylists are the best. My idea of a good haircut is one where it just settles perfectly and doesn't need any styling product.

The woman owes the barber for services rendered, plus the woman owes the lender for the money she borrowed. In this case, the creditor and the lender are one in the same.

I am also curious about why the Wiz has a dishwasher answer in his poll...

The woman owes the barber nothing.
She paid 30 for haircut and came back and paid barber 100.

Think if it this way if customer went in with 100 in her pocket and paid barber she would have 70 left.
After borrowing and paying barber and repaying the loan she now is left with 70. Same difference

The woman got a haircut and didn't pay for it. The Barber lost $30 on the transaction.
The barber, in a completely different transaction, lent the woman $100. The woman paid $30 in fees for the loan.
The woman paid back the $100, but the barber suffered lost opportunity and Expenses . We'll round it out to 20% expenses so he only receives $80 in value.
The barber lost $30 on the haircut and at least $20 in expenses. Lending the woman $100 had transactional expenses of nearly half that.
Hurray for Hollywood Accounting.

Nope, not bald. I been changing my hair style since middle school.

I started completely shaving my head in like 2006. Chicks, and even a few guys loved me with a short beard and shaved head, so I kept it shaved clean with some type of different facial hair style for along time. I can grow a perfect beard in any style I wish, it's fun to change up.

I grew my hair out during covid and kept it like that until recently. Its thinning for sure, but still looks good and no gray.

I'm now just using a doggy flobie with a 1/4 nch guard to shave it short whenever I feel the need.

Back in the day whenever I was going to a "stylists" it was 8 to 15 for a haircut and depending on how cute she was a $5 to $15 tip. But normally I knew someone who knew how to cut hair for me at no charge.

FYI my mom literally used a bowl to cut our hair pre middle school.

Why would the Barber owe any interest? I would assume if anyone owed any interest it would be the woman who owed interest on $70? No?.

Keeping the same utensils in the same compartment allows them to stack together closely, preventing water and detergent from getting in between them and cleaning. I am ambivalent about forks, but knives business end down.

I'm of the opinion that utensils go in the dishwasher handle up.
I doubt it makes any real difference during the modern long wash cycles, but it means that unloading and putting away doesn't get too screwed up if it's been ten minutes since whoever is serving as the scullery maid today sanitized their hands.

Why do you think they necessarily have to be deadbeats?

Someone could be the opposite of a deadbeat, but once they realize they forgot their wallet /purse, they might need a temporary loan for whatever reason until the next day.

It could not get enough attention while I was waiting for my haircut. I commented the dogs are good and barber says yes but they are lazy haha. They are smart.

The barber I went to for years would sometimes let me pay him the next day if it was late and I didn't have any cash. It helped that he was President of the local Sons of Italy lodge my great grandfather started. I only did that once or twice since I respect merchants too much to stiff 'em.
