What about the little old lady who is playing for the first time? She gets a little anxious so crumples the cards in her nervous sweaty hands. She takes a bad beat and mutters a few golden era expletives under her breath. Are we marching the granny out the card room?
When you introduce a rule which you enforce only when certain emotions are involved then good luck with consistency. He crumpled his cards because he was so excited to win that big pot. No ban. He crumpled his cards because he was so nervous. No ban. He crumpled his cards because he was agitated. Ban.
Casinos will need to provide a colour chart of emotions like Dulux do for paint. Then the TD can simply match the offence to the chart to discover if the displayed emotion makes a ban warranted.
Lines are not always clear and floormen are always expected to act in the spirit of a rule rather than the letter; if the granny were threatening the staff, then they might consider ejecting her, but a threat from a granny carries considerably less weight than that of an angry young man. Every situation is nuanced and it's completely correct to apply a rule in one situation but not in another.
