Traveling years ago to offshore rigs through Shetland, we were search by Shell security at the airport. It was there right to sexually assault us and go through ALL our offshore gear in an initiate manner, checking ever item in our kit bags. This tip by Shell security has now been passed onto airport staff at many UK airports. They also tried to act as HM Customs and Excise by trying to confiscate fags bought in from the rigs.
