Horrible boss/ review bomb?

My gfs boss has been foul to her and the rest of his employees since he bought the place last year, constantly calling them dumb bitches who cant do anything right even though he spend no time training anyone. Yesterday she had enough after he called her a fat worthless tub of lard and quit, well now he says hes not going to give her check to her till tomorrow out of spite. So im asking everyone to please go to Laurelville Pizza and leave a nasty review to reflect the owner
