HI
As a Ex steward
I can tell you that the reason you was told not to stand at the top of the Aisle is a question of Safety It does not matter if you stand there for a few seconds or for the whole match if there was an emergency they would need to get people out of the stadium as quickly and safely as possible and before you state the fact that you would not stand there people will as play will still be ongoing as it could take a few more minutes to let the ref and players know that the play has to stop.
As regards the swearing this is not acceptable behavour and if you happen to get the number on the jacket you could write a letter to the club the person you would need to address it to is Mr Peter Fletcher the stadium safety Officer. you would need to say where this incident took place EG stand, level, and block number.
as a matter of interest what colour jacket did he have on, orange, yellow, blue,
also which stand were you in.
Hope this helps you
