Hmmmm. I once offered to remove my trousers, but it was declined. At Gatwick once, a particularly ''keen'' security chap asked me to remove my belt. Now I was wearing a pair of outdoor trousers, the type with the zip off legs which I think are cool, but the kids take the p!ss when I wear them. They have a webbing belt which is sewn in and has one of the pastic clip type buckles. Therefore taking off the belt was an impossibility.
The security chap didn't believe I couldn't remove the belt and I couldn't believe he had never seen this type of trouser before as it is a fairly common brand. I started to undo the trousers and he shouted '"What are you doing?''. I explained there was only one way my belt was going through the x-ray machine, and that I was trying to help. He decided he didn't want to see my underwear, so we arranged a compromise where the plastic buckle ends were removed and they went through the x-ray machine.
