Yes, I was there for that.
The steward stood right in front of me when I was sitting in the FRONT row. I asked him politely several times to move, but was ignored. He was also facing the pitch, not the crowd so it wasn't for safety reasons.
I won't go back there. I went about 10 years ago, and a steward stood in front of me for the majority of the game. I don't pay good money to stare at a stewards backside.
