I dont know but surely they would have to have some way of linking the photo to the ticket as they couldnt watch 30,000 and would need the technology to highlight the ticket issue by setting off an alarm.
I was rather bewildered as to why it should happen yesterday could it have been because it was Chelsea and fairly local,. It has never happened before at The Amex.
Yesterday going into Lower West we were told to remove hats and keep them off until we were clear of the turnstiles so the cameras could capture a picture of each person. This has never happened before so has there been a problem of some description?
