轻松一刻
The fried-chicken restaurant where I was working had a big rush just before closing one day, leaving us with nothing to sell but wings. As I was about to lock the doors, aa quietly intoxicated customer came in and ordered dinner. When I asked if wings would be all right, he leaned over the counter and replied, "Lady, I came in here to eat, not fly."
