I know I could never work in security, especially for a place like a mall or shopping center, especially in my area. I have a really hot temper and if someone were rude or disrespectful and wouldn't leave or listen, or tried to physically assault me or pulled out a weapon (I live in Baltimore, so I've seen this happen at our local mall) I would probably end up fired for using force. Yeah. I'd definitely pull out the taser or the baton lol.
My last job, I couldn't stand, but it wasn't because of the type of work but more who I worked for/with.
