Please let me know if you can find anything in the Gambling commission regulations that make it acceptable to steal, though. I'll take it all back, if so.
The bit where they let drunk punters come into their joint and let them spunk the last of their hard-earned cash on a game which they know they have no chance of beating in the long-run.

Yeah, I know the punter 'chooses' (if that's a word that can be applied to drunk people) to gamble their money, but if by a random mistake the balance for once falls in favour of the punter, few people are shedding a tear for the poor hard done by casino.
Sorry, I have a very cynical view of casinos. Getting banned from every casino prob the best thing that could happen to anyone that throws money after the spinning ball.
You know what you are getting inside a casino. I am not sympathetic to anyone that loses money at the spinning wheel. It's my livelihood yet I have never begrudged a win to any person be they the biggest tosspot in the world or a genuinely nice person. My point is that I am the one getting it in the neck if I pay out by mistake and if you receive money in error, it is theft to keep it. That the game is in favour of the house doesn't mean you cannot win at it at least once.
If you're trying to beat roulette consistently then you've got a different problem altogether. You walked in the door, I didn't force you. You wanted to get drunk while playing a game of chance, I didn't make you. The job itself turns those within rather cynical themselves, particularly about those that stand on the other side of the table. It is likely that which puts me at odds with most people when these discussions arise.
Sometimes I am thankful that I mostly deal poker, these days.
