I know you're joking with this, but some people actually hates someone who win and not giving them any tip. Well, I am the one who hates and gets annoyed to the people who's waiting for someone to win to beg for a tip. I knew a lot of people who's like this in a physical casino. When they're drained they just don't go straight to their homes to rest, instead they will come and gather around you and try to give you some advices while you are trying to place a bet so when you eventually win, they'll going to ask for a tip then until they can pool enough money to play another for round.
I don't know if people like these exist in other countries, but this seriously annoys me. Having an online casino where we can play at the comfort of our home is an advantage to avoid this kind of people lol.
