Several years ago I was playing craps at the Venetian, almost always starting any roll with a $15 line bet, full odds (3x, 4x, 5x) with a modest progression on the line and the come if the shooter was making points. I ALWAYS played full odds, so when a point hit with a $25 line bet, both the dealer and I were surprised that I didn't have my odds out. He calmly says to me, "hold on", tells the box that Mr. M always plays full odds, and was given the go ahead to pay me. I thought it was very generous of the house to do that so of course I tipped them appropriately.
In Texas Shootout, a woman had AAJJ and threw in the jacks faceup. She was allowed to split once the dealer explained that option.
The thread on how many times have you seen the dealer sweep up the players chips
with a smirk would be about a hundred times longer than this one.
But I will acknowledge that an occasional event does take place,
Seldom enough that it is noteworthy.
A few months ago, at Trump Plaza, pai gow poker,
A drunk first time player mis-set every single hand.
After the dealer took a few of his chips, he started just setting the guy's hand by house way.
I guess it would have been a little much to just steal the fool's money in ten straight hands.
I have always felt that the players mis-set hand should be afforded the courtesy to be set by house way.
But again, just another unfair advantage that the house reserves solely for themselves,
even though they would still have a 2+% edge.
As a BJ player I've seen hundreds of instances where someone asked for a hit when they shouldn't have, the table screams noooo at them. The dealer says "are you sure" or something like that, and the player realizes their error and plays it right. So if that counts, it happens all the time, at least in BJ. Though you have the occasional dealer who can't wait to snap out the next card. Overall I'd say most casinos are pretty gererous with "wrong" hand signals, if you catch it right away.
It does this on online BJ in my experience as well. Try click hit when you've got 20 and a warning will come up.
But since my play is almost all at craps most of my corrections have been at craps.
I always tip the dealers with a $1 PL bet, with odds on my first roll. I will tip this for every point I make on that roll. Later, if I am doing well, I will tip by placing numbers with 'Player Control'. The dealers seem to love this tip.
I have been paid a few times on a Come Bet where I forgot to put odds on it. Since I either play max odds, or I play a consistent $50 odds, it is easy for the box to know what I would have bet. If I had made 10 Come bets and added $50 in odds everytime, and then I miss, they will usually pay if I ask.
The last time it happened, the dealer had shortchanged me on change being returned from a bet. While he and I were discussing what was wrong the dice went out, and my Come bet, with no odds, got hit. I got the box's attention and I didn't even get 2 words out. The dealer jumped right in, and said it was his fault that I missed my odds, since he had shortchanged me on a payout. The box quickly agreed to pay the odds.
If I have only 1 or 2 Come bets out, I will always work them on a Come Out roll. I had done this 5 out of 5 times, and forgot to say it. Sure enough, the 4 gets hit. At first I just said Darn it, but then I figured I would ask. So I got the box's attention, and said, "I have worked my Come bets every time, but I completely forgot to say something this time. And by the way, I always work them with 2 or less up." He paid me the odds on the Come out 4.
I have been paid a few times on the next throw, when I realized my previous field bet had not been paid. Most of the time the dealer realizes they forgot to pay it too, so that really helps (I bet it rarely, but will bet it in streaks.)
I could probably come up with 4 or 5 more if I thought harder about it. I have found most of the boxes to be very agreeable whenever I ask.
There has only been 1 time that I felt 100% that I should have been paid, and the box would not agree, so I left the table.
