So I just recently found this subreddit and figured I would share my story from a couple of years ago.

I was in the cinema with some friends watching Super Bowl. Patriots vs Falcons. We had booked our seats several weeks prior in order to get the best possible seats just below the walking area, so we could just jump down instead of having to go all the way around and inconvinience people.

When we got there some guy had taken the very center seat and refused to move. So after several minutes of confrontations and threatening with getting the usher he finally moved a couple of seats to the side. But before he could move he "accidentally" spilled cola on my seat. Now I spent the first quarter of the game sitting on a soaking wet seat. This was so fucking frustrating and I had a hard time enjoying myself for what is a fun night of tradition with my friends.

Patriots were really far behind and this guy was an annoyance constantly making hand signatures and grunting whenever the refs would make "a wrong call". We are roughly down to 5 minutes of the first half and Patriots are behind with 20-25 points and this guy goes out to get some drinks before the halftime show. As he goes away I prepare my revenge.

He had locked his seat so he could jump down instead of going around. I however had noticed this and decided to unlock his seat so it would go back and forwards whenever you move in the seat. He comes back with a very big cola and as he steps into his seat he gets surprised about it not being locked, he trips and spills his drink all over himself while me, my friends and a good chunk of the cinema burst out laughing.

He ends up leaving, presumably to go get cleaned up, however he never returned, which I figure was due to his team losing badly.

Well for people who remember Patriots overcame a 25 points deficit and managed to win in the biggest Super Bowl comeback in history and this guy missed it all because he had to spill drinks on a seat he didn't even pay for in the first place. 

I ended up feeling like an asshole but at the same time it felt so good after having to sit on a soaking seat for almost 5 hours.
