"What Time Do You Close?"

Look. If you walk into a restaurant five minutes before close, don't apologize. When you apologize, over and over, you become an asshole.  Don't make me tell you that it is fine that you are going to make me stay at work for another hour.  If the restaurant's doors are open the restaurant is open.   If you care that we are closing in five minutes, then by all means ask what time we are closing, and then leave.  If you ask and I say, "we're open until ten", and it's 9:55 and then you sit down anyway, why did you ask?! ASSHOLE!
