What should I do

For background I work at Tim Hortons and I’ve been working here for a little over 2 months. I know how to do pretty much all the drinks, I haven’t been taught sandwiches yet because this whole corona. I also take orders and cash out. I feel I’ve been doing way better and when it’s not slammed busy I get the drinks out faster than the cook does the sandwiches. But sometimes it’s super busy so they come out a little slower, or fi someone gets a late it takes longer to make.

The manager doesn’t correct me as much although I am not perfect so sometimes I mess up.

She asked me to come in today despite not being schedule and I need money so I’m like sure of course.

Everyone is being rude today. To me specifically. The one girl who usually cashes out is doing sandwiches right now and I was put on cashing out. I was told to just stay at the window so it’s not confusing because I had tried to help with the drinks while waiting. The girl on the sandwiches is being so incredibly slow but then has the audacity to yell at me for just standing there. It’s fast food not slow food and she’s going slow. Someone gave me a 50 and you’re supposed to put it in the safe and I’ve never done that so I pulled on the door and it didn’t open. So I left it in the cash register and I said something to the one girl about not being able to open it. And then she notices that it’s in the drawer and said “you can get fired for that” ok but I told you I couldn’t open it. No ones this rude to me when the manager is here. Oh and btw the lady who yelled at me for the 50 DIDNT show up on Friday and made it so we could barely have a break because it was so busy and there were only 3 of us. The person who makes the donuts and the food for the cook to make the sandwiches had to come out and help us. So I think she’s got no room to yell at me when she left us stranded in a busy situation. I wanna talk to the manager but j feel like it’ll go nowhere.

Also to add on. I’m very weak I have like 0 muscle and I’m short. So when it comes to putting the ice cap mix in my manager NEVER makes me because for 1 I struggle to even get the thing open. And then I can’t reach the machine to pour it in. The lady told me to open it and I’m trying and actually squished my finger, I told them I couldn’t get it open, and they’re like “just try” and girl I was trying 😂I literally said “I can’t magically make muscles appear that are not there” because I’m starting to be fed up. I hope the owners coming at 2 like usually cuz I’m gonna talk to him
