You buy a ticket in advance of the game for a particular seat, you turn up at the ground and expect to sit in it, what is wrong with that.
Alternatively, you arrive at the ground and find someone sat in the seat you have paid for, he has probably been to the pub for a couple of pre-match sherberts and gets arsey with you when you politely ask him to move. To avoid a scene or possibly worse you back down and go and find a spare seat behind a stanchion somewhere else, your day out has been pretty much ruined because of this regardless of the result, you probably don't feel like going away to watch your team again.
