A few times a year I end up in a TSA line where one TSA person is shouting instructions to everyone, and 20 feet away the next is countermanding those instructions and seems exasperated that everyone is doing the wrong thing.
It's such a bad joke.
A few years ago I went through an airport that had a dog checking everyone. The handler was struggling to get the dog to do his job, people were not being checked, dog / puppy just wanted to play.
