LHR T1 Security
Coming through LHR T1 security (PAX) yesterday evening, I was in a line where everyone was asked to take their shoes off for examination....no problem at all, except that in the line beside me, the people were being told that there was no need to take shoes off.
When I asked about this after I passed through, I was told its a random examination that they do at LHR T1...great idea, except that if I did not want to have my shoes x-rayed, I could have picked the line to go through to make sure they were not looked at!!
