I had a rather upsetting experience with TSA in SFO and 120 film.
Film was in Kodak sealed boxes in a clear plastic bag.
They opened the film boxes and then ripped open all the foil wrapped film w/o even asking or telling me.
I was getting ready to shout at them, if they even looked like they were going to unwind the film.

Geez what would they have done with 4x5 sheet film?
