you've gotten some good answers...
Here's some things to look out for.
(1) you are playing and the pit critter walks up, picks up the discards, glares at you and your bet as he "appears" to count down the deck at high speed. Most likely he can't even count his fingers and toes, but he does the act convincingly. How do you act?
(a) get quiet;
(b) leave after the hand is played;
(c) ask "what the hell are you doing, checking for a missing card or a dealer mistake? You are slowing the game down too much..."
(2) you are playing and the pit critter walks over, maybe from a "cheques play" or just because, and glares at you as you play. How do you respond?
(a) get quiet;
(b) leave soon;
(c) complain about losing your shirt and asking for a comp.
(3) your half-shoe happens.
(a) (b) same as above;
(c) Say something like "OK, if you are going to cut off 1/2 the shoe and waste all that time shuffling, I'll just go somewhere else to play" or else just play as if nothing is happening.
It will be unnerving the first few times you encounter this kind of "heat". But if you react reasonably, you can turn it around and make them think you are a real idiot, which is your goal. It takes nerves of steel (that's why I'm a stainless steel rat... :) ) to avoid letting them "get to you". Just don't start flat-betting or doing something "different" which is a form of "counter tell" they will be looking for. Show 'em nothing, and often they will crawl back under their rock for a while...
