Horrible Customers:
I used to work at a restaurant that had a large outdoor deck. I mean huge, it had it's own large bar, more seating than the inside of the restaurant, and a stage for live entertainment. There was also a pitiful little playground area with two swings and a slide. One day a server noticed that three kids roughly 5-7 years old had been playing on the swingset for over an hour without any adults. She alerted the manager, who scurried on over and asked the kids where their parents were.
The children had no idea. They were under strict instructions not to leave the swingset until their parents returned. An announcement was made, but the parents weren't in the restaurant. The police were called, and the parents were eventually located. At a different restaurant. All the way across town. Unbeknownst to us, two couples had been dropping their kids off at our deck twice a month so they could go bar hopping without having to hire a sitter.
