- Why would a dealer not always keep a deck low and level?
A dealer who does not keep the deck level is ignorant or lazy about good dealing procedure or cheating you. Rolling the deck is just plain sloppy dealing of the worst kind.
- What is going on when they roll a deck? Is the dealer cheating or just lazy?
More likely then not the dealer is just lazy. Shame on that dealer, and even more shame on the management that lets that dealer keep their job. When management does not insist that dealers know and practice good deck handling skills, they are opening the door to cheats in their poker room. If you ever find yourself in a card room were some or a lot of the dealers are not keeping the deck level, you are in a place were you will be cheated eventually.
Rolling the deck is a drop dead easy cheat. Setting things up with a player at the table is not even necessary. All a dealer needs to do is make sure one of their favorite regular George's sees a card once in awhile. Some lazy dealers are not even cheating they are just flashing cards because they don't care. Some are simply rolling the deck because they don't like you, and will flash to other people so you hopefully loose.
