I don't remember the exact circumstance but I had a TSA jack wagon tell me to do something that I had never had to do at any airport. When I kind of questioned it politely he basically told me what a dumbass I was for not knowing how TSA operates everywhere. And you can't say or do anything or you risk not being allowed to fly. Freedom. Edit: forgot to add - it's not like my other airport sample is small. I imagine I have been in 50+ different domestic airports in past 5 years. That estimate may be low.
