About the privacy cover thing which seems to be the most controversial thing on my list, the privacy cover thing is to prevent shady low lives from looking at your slot while you are playing. If I am at a slot machine minding my own business, and I get a $500 hit on a very lucky spin, I don't want some low life telling me,"Oh, what a great hit! Congratulations! Oh, by the way, I just lost my money for the week on a bad slot machine . Could you give me a $20 for the week? I mean, you do have an extra $500 win!"
A guy said on.another website that he won exactly $500 in a lucky drawing. But in order to claim his prize, he had to accept it on the very public stage. After he got the win, two burly men he had never seen before went near where he was playing with his won money and started giving sob stories about losing their money in slots and claimed they were hungry and strongly suggested he treat them to dinner at the casino restaurant with the money he publicly won. Luckily, a slot attendant was passing by and the guy gave her a look that clearly said,"Help me. These guys are harassing me," and she got the message and said something like,"We don't allow patrons to just stand around watching other patrons play. You guys will have to leave if you are not playing." She got the burly men to leave and he tipped her for helping him out.
In both The Hunger Games and in gambling, may the odds be ever in your favor. :D
