When is it okay to touch a waitresses ass?

Answer: NEVER! You would think this would be common sense, but some pervert brushed his hand against my butt, and it was not by accident! The douche had plenty of space to go past me without doing this, so why would he do it? Because he is a disgusting pervert! I feel incredibly sorry for his wife, who coincidentally had 2 glasses of chardonnay (and probably more alcoholic beverages when she got home). My entire day was ruined from this experience. So thank you, jerk!
