How do you handle this one? (Bad conduct and worse conduct)

It is bad manners to expose your hand or just show one hole card in a cash game but not against the rules in most casinos.

Are you sure about that? I believe MOST casinos make it against the rules to show your hand in a multi-way pot. While they may allow it heads up, it is consider a big no no in a multi-way pot.

Often the floor will just "inform" new players that it is not allowed .... but they will often punish players for such purposeful abuse.
