Do I quit now?

I had an interview at a sandwich place last wednesday. I got hired on the spot. I started the next day at 10am and have been working since then everyday. They barely trained me and make backhanded comments abt things I don't do that they don't train me on so I don't fucking know how to do it. They tell me to go home on a slow day so I go home, but apparently I'm working whatever a split shift is so I need to be back for the second fucking half that no one told me abt and it's my fault now for not reading the schedule right but you fucking told me to go home for the day bro. Anyways do I quit because I hate this job and it's making me hate everything idk why I applied I hate food industry so much and I just want out.

Sorry for the bad typing I'm a mess rn but also if I should quit, what do I say to the manager that I'm quitting cus the paper said smth abt at will or whatever?
