My ex-boyfriend was an extremely avid gambler so we got comped all the time whether it was a room, an upgrade, dinner, spa services, etc. Well he went on a crazy winning streak and the next time he talked to the casino host who normally gives the upgrades she said according to his players club card he had a 40% win ratio (and the average is about 4-7%) so unfortunately we aren't able to comp anything at this time. It was crap. But I guess it made sense... I doubt that's the case everywhere but it happened. I stopped using those damn players club cards after that.
