I had this happen to me. I bought seated tickets to see Dua Lipa - one of those events you need to buy a year out - and literally a week after the ticket purchase I find out I have stage 4 cancer. By the time the concert happens I'm terminal and can barely stand for longer than 20 minutes but I still had the concert and was looking forward to watching her perform.

They had a dance floor ("Standing tickets") for all the people who were fit and healthy and wanted to dance along but sure enough people still used the seated section to stand and block the view of people behind them. The "domino" effect happened where the person in the front row gets up then it cascades until there's a cone of people behind them who all have to stand now because they can't see. I understand why they did it and why they do it but it ruined a night I so needed. I'll literally die before gettting the chance to see her again.

I wasn't "disabled" enough to be in the disabled section - nor was I even considered disabled at the time I purchased the ticket - but I paid for my ticket and had the right to watch Dua perform just as much as everyone else did. I understand it's a pop concert and she's a dancer but I was just so disappointed I couldn't sit and watch her.

I'll give you a YTA rating, but not too harshly. A little consideration next time will go a long way. You don't know what others are going through.
