Just today, I was at a favorite diner spot in my hometown, open until 1 PM. I know the owners somewhat. MY SO spends a lot of time with a few of the family members at community functions. A young couple with a child came in at 12:35 PM and they close at 1 PM. One of the owners rolled her eyes. Made me think. Wondered how late is too late? Do you go up to one hour before closing? What if it is a buffet and you are in a hurry? What is the etiquette here?
No, I didn't ask her, though I might have. I got there at 11:30 AM ;) with my gang.
