Worst Person You've Ever Worked With?

Just wanted to share stories about the worst person you have ever worked with. Here's mine:

I interned for a loan company once and the production manager was a childless, divorced middle-aged woman with a little dog named Lacy. She was a police officer before getting hired as a secretary at the firm. She worked her way up to production manager. Her job was mostly inputting applicants SSN, DOB, etc for the underwriters and checking which process the loan was in. However, since she has been at the firm for 15 years, she thought she knew how to do everybody's job. She played the same ten songs over and over again ("Boogie Shoes" is one of them), yelled, and cursed.

I was supposed to be split evenly between her, the closing officer, and the president. She would start yelling at me because I did not do her rudimentary tasks before the presidents more in-depth assignments. I would just tell her the president said this was more important. She'd get mad.

She bad mouthed me to everyone in the office, saying I was too busy listening to my headphones than actually working (which was BS because she blared her music all day) and I was trying to steal her job.

On my last day, she told me I needed to be kinder to people and stop gossiping about her. She said I was rude, had bad manners, and tried to out-dress and out-smart every one in the office because I thought I was too good to do the rudimentary tasks she assigned. She then wanted to hug me and asked my future plans. I told her I would consider her advice, and I was applying to business schools. She said "hope you can afford it."

Psycho Bitch.
