This sign hangs just past the X-Ray machines in the Milwaukee airport. This is one of the first signals I have ever seen that the TSA actually “gets” it.

I used to think (and have stated) that TSA stands for Thousands, Standing Around. And every time I go through security at an airport I see both silly letter-of-the-rule applications and failures to follow their own policy (in 4 flights no-one asked me to open my metal coffee container, which is x-ray proof, but they did give a teammate grief about his 8oz of hummus. He was let through.)
