Then you are playing at the WRONG casinos. No wonder you don't like Vegas.
El Cortez IS sweaty, hence the nickname. I recently saw them backoff a dude spreading $5-25.
Despite having just said that, my experience has been that most players don't understand EC. I play there several times a week and have had no problems in about 7 years since Maurice "Mo" retired. The key is you have to identify what is and isn't tolerated and stay within their comfort range/level. This has to do with betting limits, spreads and length of session, and no this doesn't mean you have to play $5-$20. This "identifying what is tolerated" is how I play everywhere, but EC, it is mandatory.
And what is tolerated by one pit person may be very different than what is tolerated by another. Take Dragon Lady for example. Yes, please....somebody take her somewhere else. lol.
