There is one major casino/hotel that comps me rooms. I get there, check in, then go to casino and start playing anonymously with toupee and bottle glassses. Within a few minutes, the pit addresses me by name (must use face recognition technology), says I can't play BJ. I leave. I still stay there all 3 days with no problems. Sister properties let me play with no problem either. This is in Vegas. Weird!
