At Schiphol airport in Amsterdam, hand inspection of my few rolls of delta 3200 was refused, when I requested it, after sending the rest of my film through the scanner. The inspector insisted that hand inspection would mean opening each roll, and unrolling it. When I asked to speak to his supervisor he said he WAS the supervisor.
The film went through the scanner. Hand inspection was done at other airports, that trip, including England - might have been Manchester rather than London. The film was OK.
