Good one today at LHR. Staff search has a sign up saying random shoe search. But the guy at the scanner gets very ar5ey when everyone is not taking their shoes off. He then shouts at someone "the sign says everyone should take off shoes" to which a few of us tell him it doesn't. Does the sign get changed? Does it hell! So I started my day a little annoyed that someone had shown me a bit of attitude for following what their sign said which was not what they wanted me to do??????
