Just ask for hand inspection.
I've also had issues in "important" cities, like when I visited Washington DC I wasn't allowed in the LIBRARY because they needed to x-ray the film and I wouldn't allow it.
What I noticed more than anything was that because the cameras had removable lenses, they insisted on looking inside OR x-ray, I chose X-Ray and when I got the film back all the rolls that were IN THE CAMERA at the time of X-Ray all had terrible banding.
I don't know if its something in the metal body of the camera that amplifies the waves, but it's bad.
So always finish off a roll before going through the X-Ray... That's my biggest advice.
This banding BTW was on ASA 64 film... Very slow...
