Quoting Curlyheadedfck:" i always feel like doing this at work with menus when people self seat themselves "
Ughh I know that feeling.
And then when I worked at Waffle House where it was ALL seat yourself, it was the ones who would sit down while you were still trying to clean the table so you had to get AROUND them to clean the table off and it's like, "Uhm, excuse me! Do you not see that this table is NOT set up for seating yet? I clearly realize that you don't want some other family to move in on your table, but you could at least stand at the end of it so I can finish cleaning it off, thanks."
