So I started a new job. And it's humiliating!

So recently started a new job 5 days ago taking orders at a local pizza place. I love it. Except 1 thing. THE BOSS IS A DOUCHE BAG! When I'm taking orders on the phone he yells at me while there are CUSTOMERS standing in line. Now I've never worked in a restaurant before so I'm new to this. But he just takes it way too far! When I was working Sunday, we had just opened at 3:30pm I got there at 3:20pm ya know to be early and what not. I took an order over the phone, and after I hung up the phone, I asked my boss "that's how I would write this, right?" He had the nerve to say "Jesus Christ! Do I have to send you home early already?!" Like wtf!? I'm still learning the pizza lingo. I'm fucking 30yrs old and wanted a part time job just to have money for myself. But I will not be treated this way! Any thoughts or opinions would be greatly appreciated! TIA ❤️
