Airport security is irrational. They can never decide how many trays they want you to use. Put jacket on top of computer vs seperate tray. Stack computers vs not stack. They keep saying shoes on, but with protective boots that's just stupid but some won't listen. With the newer hands up to the sides machines they always say not to take anything off, but they always trip on the shoulders on my wool shirts and then they spend a while searching.

Screwdrivers they only bother to steal like 10% of the time.
