I hate where I work

I hate where I work I hate McDonald’s so much ( I do it with college btw) . So many customers laugh at me while I really struggle to talk. ( I do the front areas so clean tables etc. ) and then you get coworkers or managers going “ oh you should smile “ or “ you look annoyed “ You wanna know why I look fucked off. It’s cause customers fucking humiliate and verbally mock me and my speech disability!! Oh sorry I really should smile in such a wonderful work place as this where every time I come into work I get needless insults and by the end of the day I’m almost in tears. I couldn’t give a shit how it looks to customers. If anything I’m showing them the real face of the fucking company to those who join. Literally near the end of my shift I just wanted to be alone so me and the closing cleaner ( we both clean lobby ) agreed to do the downstairs while I close a little of the upstairs while I listen to music to calm down. But no I gotta go downstairs. I end up nearly crying so go to the back and listen to a song or two and just try make it through the last shitty hour. I hate the fucking laughs I get from people when I desperately try get my words out stammering. Assholes imitating it or others deliberately trying to get me to stammer by asking me to say certain phrases or words ( suffered this through high school ). I hate this place. Managers act like it’s the fucking Truman show and we’re always happy !
