First time I have been to a casino and was a little worried I would not know what to do or if I made any faux pas. All staff were very friendly and politely explained to me when I made a few errors. Brilliant first experience and will definitely go again.
Not sure if they are genuine or not but I noticed a few drunken groups/individuals rude to the staff and croupiers because they were either drunk / losing or both so personally I would take complaints against staff with a pinch of salt
