I had a security job for 2 weeks.
Jobs were scarce and this ghetto startup had openings, so I took something to perpetuate that eating thing.
I regretted it. I wasn't a mall cop, thank god, but I was there to pit-lamp hobos at one construction site and the next week moved up to patrol a pulp mill after-hours.
In those two weeks of skulking about I saw a lot of nature - mink and eagles and such - but I couldn't take the mediocrity and shady management; so when another opportunity came up I bolted.
It's funny but that's my worst.
