One of my pet peeves with TSA.doncb wrote: Got pulled out of line because of a small jar of change. Was told I needed to leave my change at home.
Good officer response: "You didn't do anything wrong, it's just we can't see through this much change so we have to check your bag. In the future if you leave your change at home or carry it in a separate bag it will get you through faster."
Bad officer response: "You need to leave this at home" **Usually said with a scowl and condescending attitude.
