Really sorry but I havent read the 7 pages of this thread, so sorry if this is repetitive.
I found out 2 things last night
Someone got a junior membership for their 24 year gf. How have they allowed this to happen, IIRC for ST originally you used to have to show a birth certificate?
Secondly, we had a last minute drop out so we gave one of our tickets to a friend of mine. He's been to a few games over the last decade so I didnt feel bad about it. When he got to the turnstile his pdf ticket didnt work, I was already in the ground and was told if we could show her the membership card related to the ticket she would let them in, which surprised me. The card was in with the rest of the group who were in the stands, so I went off to get it. Halfway back to the turnstiles they had let him in anyway. Where is the security in that? You could get a ticket, print it off twice and then sell one of them on.
