Can I Sue, If so for harassment? It was bulling too...can you sue for bullying?

I worked at a restaurant. 1st day the manager points out a girl said that's why she's not front house server. She has missing teeth. I was like awww:(... Third day in I noticed a male manager not being professional making unwanted jokes to the `ugly' girl. I was like if he talked to me that way I would be so upset. Sure enough second week in he said come run you food retard. I was like please don't call me names. I said I've noticed your not the most professional person so let me just work ..I'm not here to be bullyed or make friends. The every time I'd walk into the kitchen he would throw celery in my hair, flick each at me randomly screen in my ear when I was unaware he was around. He plays favorites with ones who he got in the bed. I ended up quitting because my anxiety got too high I just couldn't take it anymore. I went to manager, even owner, nothing done about it. Told me that means he likes you. Whhhat!? I understand he owes the owner money....maybe that's why he is still there
