Input: Text: so, i am a maintenance guy in a factory. i am sitting here on reddit just browsing and all of a sudden, my stomach cramped up. so i walk out of the office and go out of the maintenance cage. we have a cage around our tools and supplies so other people cant get to them and steal them. no joke people have actually stole mops from us. anyways, it is a rule to close the cage when you exit. the cage to the door is self locking so i shut the cage and rush to the restroom. i am sitting on the toilet and look at my belt. at that point i realized i had fucked up. i left my keys in the office.... at this point i strain and get out all i can until i feel that my stomach is eased off enough where i can last a few hours. i walk to the edge of the cage and see the office. luckily i didn't shut the office door inside the tool crib and i can clearly see my shiny keys laying on the desk. i didn't want to look like a complete idiot so i didn't call a fellow tech to come open the gate for me. no that's just silly. looking around i see a metal bar. taking the metal bar i push it though the chain links and pull over a cart with tools on it. reaching in i grab an allan pack and get out a .05mm allan wrench. i reach down on my belt and pulled out my multi-tool. i praise god that i always carry this thing on me. pulling out the tension wrench on it, i inserted the allan wrench into the lock and my tension wrench in the bottom. here i am on one knee trying to hurry and get this open when low and behold, here comes a security guard. right as i turn my head, the lock turns and the cage comes open. he witnessed a breaking and entering. i stood up and looked at him and he looked back at me. there was a moment of silence between us two as we shared a moment of tension, a mexican standoff. he then comes up to me and grabs me by the back of the neck and pats me down. all while he gets on the radio calling for more security. all the time my face is up against the wall, i'm blabbering trying to explain myself. he then grabs my arm and here comes the backup. to make a long story short, i spent 2 hours explaining to them i work here and i had locked myself out. after i showed all the evidence they laughed at me and let me loose.
