Input: Text: so this happened two days ago. i work at a supermarket chain, as a cashier. been there for about four years. pretty mindless job, the pay sucks, but it is a job noneless. 
so anyway, there are a lot of younger girls (early 20's) that work at the same place, doing the same job. we don't count out our drawers, or have key locks on them - for some reason management thinks this is a good idea. we also have two video cameras in the entire store, one in the backroom, and one facing the parking lot. that is it
so on friday, one of the newer girls, who must have been working for about 3 months or so, comes barreling out of the managers office in the evening, her face beat red and balling her eyes out. apparently her register had come up short for the day (by 195 dollars), and my boss was threatening her with firing and arrest.
now i really don't know this girl very well, other then she is a single mom, trying to make ends meet, seems pretty normal enough.
this is where the fuck up happens. for some reason, i'm not sure what came over me, i stop in the path of my boss, who was in the process of following her out of the door, and start completely throwing myself under the bus. i told him i was on her register all day, and that i had told her to go check product dates instead. after giving me an incredulous look, and unleashing a barrage of yelling at me, he basically told me to get lost and don't come back, and expect to be hearing from the police. none of this actually registered until i left the store, what had happened.
so now i'm out of a job, so low paying that i don't even have a savings, and will probably be booted out of my apartment, and expecting to be charged. all for a girl that, for all i know, skimmed money out of the register.

TIFU by taking the blame for a coworker - and now probably getting arrested.
