Input: Text: so unlike most tifus this actually happened less than an hour ago. so i've just got back from watching the hunger games: mockingjay part 1 (just the title makes me yarl). the movie was 'ehh' but what happened next was class.
    the cinema is like a plaza and all the screens are above each other connected by two stairways. one goes to the reception via the entrance lady's bathroom and the other one via the men's, or so i thought.
    i mentioned to my family that i was going to the men's room as we left the screen. i nonchalantly walked down the stairs and i did my business, once finished i carried on walking downstairs to what i thought was the reception. i was acting too 'cool' to realise that i just walked through a double door labeled 'fire exit'.
    i was taken aback when i realised that this was not the reception and instead a small room with a big window door thing, with a label across it saying 'this door is alarmed at all times even when the cinema is open' 
    i then realised i fucked up and tried to turn back and leave to find that the door could only be opened from the inside. shit. i was locked in a room where one wall was just a window. to add insult to injury, everyone from the cinema could see me and my embarrassment. i quickly phoned my dad and pleaded him to save me.
    after 5 minutes of laughing at me through the window he finally agreed and made his way towards the mens room. (i later on found out he got lost and walked right through a screen showing 'my old lady')
    my guilt and sadness turned to excitement when the door next to me opened up and he stepped inside laughing at me. he was so preoccupied with laughing at me that he forgot to hold the door open and it closed on him too like a horrible, horrible trap. i will never forget his face when he realised that he too was locked in.

    after a good two minutes of knocking the door was finally opened and we rushed out to find a confused teenager holding it open.
