Any player with an ounce of dignity would surely act in a gentlemanly/Ladylike way and therefore make the dealers job that much easier which would then add to the enjoyment of ALL.
Or do these players that feel the need to act like complete jerks (maybe it's not an act) think it is humorous and clever to try an belittle others?
I have seen this so many times when a "newbie" dealer is bought to a table, some people go out of their way to make them feel as uncomfortable as possible - it seems I am always doing the opposite, trying to make them "feel" relaxed so as not to make too many mistakes
THE worse thing you can do to a nervous dealer is badger them on every little mistake they make - it will then lead to more mistakes.
I have however had a quiet word with a TD when a dealer is just not up to scratch to have them moved from the table, but this is just as much for their benefit as to the players at the table - especially if the table has a couple of players on that I KNOW will hassle an inexperienced dealer.
