So we charged hourly rates of say $3 to play games, or $20 for all night until 6am. My job was to get people to stay. If someone comes in and plays a few rounds of counter-strike we make $3-6, but if I convince them to play Starcraft, Baldurs Gate or Rainbow Six they'd stay all night. I would encourage people to join me in games like R6 and we'd spend bloody hours on the game. I was also good enough at CS, HL etc that if we played a tournament I could "just win" and again get people to stay and try again. I miss the muscle reflexes of 19 year old me.
