My friends and I went to city screen to watch the new Spider-Man (12A). The tickets were a reasonable price. So we went ahead and bought tickets. It was a very miserable day as it had rained. We had arrived 5 minutes early to go to the toilets and get settled. As we were about to enter the person who examines are tickets pulled us up and asked If we had any ID. This confused us as our other friends had already gone in. We were 13 and were unfortunately not carry ID with us. We think they stopped just us going in was because of our height as we were the smallest of the group. In order to prove we were allowed to go to watch the film I offered them to ring my parents and even see our private social medias. They still didn't accept this. So we were forced a refund. I can agree that they would be concerned that we didn't have ID but they could have told us straight away rather than us going through the whole experience.
