Taking showers at KFC? what?

I recently read an article in the Star Tribune about 3 former employees at the well know restaurant, Kentucky Fried Chicken in California. The three of them were closing that night at KFC alone with no manager, and they were told to close later that night. When they closed, they decided to pull a prank by putting on their swim suits, and taking a bath in the giant tubs in the kitchen used for washing dishes...not people. They were obviously not thinking when they took pictures of it and posted it on facebook. Of course, the manager found out and they were all fired. This probably won't help them find another job when someone is informed that they take baths in kitchen sinks...
