Well, you definitely hit on a couple of my big annoyances in your list, the biggest is people drinking, well, more like getting drunk at the casino. While I’m not opposed to having a few drinks, someone who is drunk and affecting table play irritates me to no end.
I think one thing that might be added is not to play angry. I have seen so many times, when people are losing, the frustration kicks in and they start using foul language, yelling at the dealer and sometimes other players. At this point, things usually only get worse. If things are going badly, and you aren’t having fun, walk away for a bit. Go and get something to eat or go home for the night. The casinos will still be there next weekend.
