See the latest joke at LHR and LGW is that for ground staff, they are not allowed to wear metal capped safety shoes. The BAA have said that it is to stop the alarm going off, and prevent injury to the security staff due to having to bend down when 'patting down' the 'offending' staff member. Poor little luvies, musn't let them bend down...oh and if you wear a belt it must be undone so they can feel around it OK !!! Cant wait to see a big 'large' person go through, have to undo his belt, have his (or her) trousers start to fall, go to hold them up, get told off as their arms arn't outstreatched!
