AITA workplace conflict

I was working fast food And I was working with a fellow employee that I made cry after I kept complaining about her work problems even though she has done the same to me plenty of times, For example I ask her about pickles on a sandwich and she says it should be fine And then I give it to the customer and we both have to check It's not fine I have to remake it and I tell her it's not fine and she goes complaining to the manager, multiple times she complains about how I make food how I pour out some ice to give a more fair amount for tea because we all know corporations give way too much ice into the tea to scam customers, I was making doodles on the day sheet earlier that day and she complained to me that I wasn't getting paid to doodle I called her work pilled I didn't even have any assigned tasks​​, She's not a manager In fact she's under 18 She's been working there longer than I have and she's the little sister of One of the managers, She keeps telling people to do things even though she's not in a position of power I tell her that she's not a manager after she tries to kick me off of fries even though​She doesn't have the authority to, She constantly keeps telling me to sweep the kitchen but if it really mattered to her she would do it herself, And sure I complained about her not doing her orders properly and called her out in the same way after she did to me that day saying that she's not being paid to beg and that she shouldn't be focusing on talking instead focusing on working Giving her the exact same treatment that she gave me, And then I get called into the manager's office saying I should just listen to her instead and got kicked off early after she broke down crying. She's just a kid I know She mansplains things I already know how to do and acts like she's the boss of the kitchen.

Deepest regards I don't know Am I evil?​
