At least the screener knew what most of the things were.

Reminded me of a story where a famous Australian female athlete was going through security at the Beijing Olympics (she was not competing). Security was very tight. Her handbag was x-rayed and pulled for inspection. Army personnel went through it (all male crew) and found the offending items. Several bullet shaped white products (of a large calibre) that he was highly suspicious of. Australian female tried to explain for several minutes, using some discrete hand gestures and english to the non-english speaking male security what they were. After two minutes she found a female security person. Result: One red-faced security officer.
