To the OP - I've resisted making similar grumbles on here as I didn't want to overshadow what was a great day.
I think I may have been sat very close to you. When these guys started having a go at my uncle who is a ST holder and has been going for 57 years for asking them to sit down I almost lost it. We missed the first 10 minutes or so as we had to pear between them. There was nothing we could do, it totally ruined a great night for him and us. One of the guys did apologise buy it was too late at that point. Their comeback was 'I'd like to see you at an away match", which totally baffled me. I'd like to blame it all on the occasion and the booze but I'm not sure that made too much difference.
At most away games you have a choice of where to sit, we were just unlucky that we weren't able to move on this occasion.
