Fletcher's post, as usual, is right on the money. A good book will keep tabs on most players. If you scream and holler every week that the total is wrong, etc. - you will get no slack or be asked to go elsewhere. If you are a stand up guy, you will always get the benefit of the doubt. Funniest story i know goes contrary to this. Had a friend (passed away) that probably lost at least $150,000 a year playing horses with book. Many a week would go by with him down 7-8k. One day the phones went down and he didn't get his bets in. He ranted and raved (normal for him) and said he would have won $5,000, etc., etc., etc. You should have seen his face when they paid him the 5k. In this case, it was a good investment as he continued to lose.
