When traveling, it is wise to wait until you reach your destination to buy film—give yourself time, or just bring the minimum. At the end of your trip, hit the one-hour lab and at least have the film turned into negatives—once developed, they can not be harmed. You are totally at the mercy of the inspectors.
On a forum a decade back, a travel photographer described how he asked for a hand inspection of a three-week shoot in Germany. The guys running the machine knew that he had a plane to catch, and also knew it was very difficult to sue across international borders. He and his buddy ran the shoot through the machine repeatedly—because they could. They though it was hilarious. Three weeks of work destroyed, and nothing to show his editor. Yeah, he was bitter.
