Input: Text: so today me and my friends went out to a local cinema. we decided it would be a good idea to go the local corner shop and buy cheap snacks. this cinema is in south-east part of london, and for those of you who don't know, here even glancing over at a person for a second can get you into an argument. so while we were in there my friend couldn't decide what to buy and me being me.. (oh i should probably mention that i am a white fellow and he is black. we have been close friends for many years and think it is funny to make racist jokes about each other time to time)... shouted from the far end of the isle "omg stop being so black and stealing that bag of doritos" and before i could finish this sentence my friend was shaking his head, clearly telling me to shut up, but i didn't understand. with my luck, these group of dark coloured gentlemen heard my overwhelming comment and decided to take action. 

i didn't know what to do so i just ran. and ran. and ran. i could hear/see/feel cans of whatever beverage they were drinking being thrown at me while i was running.

so i ran to the nearest bus stop and got on a random bus. i am shaking, i am panicking and i am incredibly ashamed.

TIFU by not realising I was in public
