I was attacked by rats in the cinema before !!! Beat that !!!
Seriously, that happened earlier this year.
Went to watch Four Christmases (2 weeks after Christmas !!!)   ...which meant the hall to be quite empty
Just a few minutes into the movie, saw something ran past which I suspected to be a rat but did not give it much thought as I assumed it could have been my imagination or just a shadow.
A few more minutes later, I noticed something furry standing on the "valley" of two seats right in front of me and curiousity got the better of me and I leaned forward to get a better look.
It was a rat which jumped onto my lap and I took a swipe to get it off me.
Next was the cinema staff who brought in my food, which I complaint to him informing him that there is a rat and got a seriously WTF response of "Saya tak tau" and he walked away.
The final straw came at the 30minute mark of the movie...the rat did a free fall dive onto my shoulder.
Pissed off and demanded to meet the manager and go a WTF response v2 of "Biasa la ada tikus".
Stupid manager even thought of not refunding me. 

Then there are the usual others
- People behind kicking our seats
- People taking off their shoes and dangling their stinking feet near your head !!!   
- Stupid parents who bring their children and allow them to be a nuisance inside the cinema
- Talking aloud during the movie
- The deaf narrating the story to the blind (where you have one person explaining every thing on screen to another person, eg: Screen showing the hero with 2 bullet wounds and the deaf go "The hero got shot twice" to the blind) and the translator (which one person translate everything on screen to another language) Seriously, this kind of people seems to frequent the cinemas more and more often as I am encountering them on a more frequent basis.
