when an supposed gentleman shorts any provider. I appreciate it when a provider leaves the envelope to open at a discreet moment or after I leave.

That said you seem to imply that a regular does this more than once. IMO if he shorts you once...you need to let him know. I think a nice e-mail should take care of it. Better to lose a bad client than to get shorted again...not to mention the aggravation you have expressed.

Since you seem to have more than your fair share of problems you need to change your proceedures.
