As a side note, I should add to be friendly and confident, but keep the conversation as boring as possible so the boss won't legitimately gain interest in speaking with you!
Or to take it a step further, start harrassing the pit boss like a ploppy, complaining how you played for an hour but can't get a sandwich, how many more hours do I have to play to get a room, stupid grubby questions about promotions, etc.,
Then they'll outright want to avoid you!
So if the pit boss is glaring you down, point an accusatory finger at them, and just start off the conversation "There you are you sonuva b*tch! I've been playing penny slots for 30 minutes, why aren't you giving me the presidential suite!"
