This is nothing. I work in the Nevada casino industry. Last weekend we had someone win $20,000. They tipped the slot people who helped them not a dime.
I used to work with a BEAUTIFULLY stunning cocktailer in Biloxi. A guy won several million on a slot and tipped not a soul. She said another guy (some famous baseball player) tipped her several thousand at a VIP table and later made it clear that he expected some [deleted] for that money. She laughed at him.
Gambling is expensive enough, now you want me to give money to people?
