(this might be a good post in
Brick & Mortar Cardrooms )
There are not many professions where taking verbal abuse is part of the job.
As a (male) dealer myself, verbal abuse is not tolerated at all. In fact we have signs on every wall of the room that state that dealer abuse is unacceptable. We have a three strikes rule.
One warning comes from me...something like, "Sir, relax and tone it down or you will be asked to leave." Sure, snide and immature little comments are frequent and usually ignored, but "abuse" is not (throwing cards, dropping f-bombs, name calling, etc.).
Second offense, the floor is called. Third time and he/she is tossed out.
The abuse used to bother me. Now it's just the same crap from different faces.
