My mate and I tried to check-in before walking to the match, but being too early, we were offered a locker. After the match, we're tired, we just want to go to bed - and the woman behind the desk starts insisting on picture ID - and wouldn't even let us into our locker before ID'ing us. A) we were never warned that this was a requirement. Then B) she wouldn't accept my 60+ oyster card picture verification. Despite having a bank card and a number of credit cards, she still wouldn't accept my oyster card picture (which was recent, I'd only turned 60 2 weeks ago). Neither of us were carrying a license or a passport, we'd only traveled from London by train. Eventually, I found a medical card which she accepted - but this was after frustratingly long 20 minutes. She was wholly and utterly unreasonable and indeed, the request for photo ID was as well. Visitors beware.
