Laura,
I like Chet's advice. If you are looking for answers pertaining to the employees of the card room, as opposed to the players, I will try to give you some answers.
I will start with the waitresses. They must be:
a.) Pleasent- even when they get stiffed by a player. So....they can't be grumpy, or miserable, or sarcastic, or solicit players.
b.) They must learn to observe the action before they approach the table. They must be sure that the player they are serving is not involved in a hand. This is important because it can disrupt a players train of thought, annoy some players, and result in "no toke."
c.) Don't keep player's waiting, only to receive a cold cup of coffee. So....They can't be too slow. They can't talk with their friends, or anyone until all of their drinks are delivered.
d.) If alcohol is served, know when a player has had enough. So.....they should alert others when a patron has had too much, (bartender, floorperson, or even security if necessary).
e.) Be fresh and well groomed. So...... Never be unclean. Never wear overpowering cologne.
f.) Smile and say thank you. Never bring personal "outside problems" to the patrons.
Cashiers, chip runners, other card room personnell:
a.) Be Friendly, and smile. So.....do not bring a bad attitude to the cardroom.
b.) Be efficient. Know all procedures and be an expert at chip/cheque handling. So....cage shortages are unacceptable.
c.) Be accurate. Never short-change any player. So.......a dishonest, tip hustler in your cage is unacceptable.
I will continue another time with the dealers and the floor. I have to go for now. I hope this gives you some answers you were looking for.
