It's an hour before closing, and I'm on driveup by myself, of course. A lady comes with an order with more than 100 items, heavy cat litter, a bunch of water, etc. It takes 2 full 5 for all her stuff. She didn't double tap, which I appreciate, honestly. So she gets to the store, and I tell her to pull up to the doors so I can load her stuff cause little old me can steer 2 heavy carts all the way out to the driveup area. I'm putting all her things in her trunk. She doesn't help because why would she. I finish one cart of her things, and the cart somehow rolls away and hits her car. I looked, and I didn't see any dents or anything. I didn't say anything to her or apologized I just continued putting her bags in her trunk, which I know I should have. I was just upset I'm doing all this all by myself, about to give myself a rotator cuff injury from picking up all that litter and I wasn't even supposed to be on driveup in the first place. Also, usually, if I ever have a big order (not even 100+ orders), the guest comes out and helps; common courtesy. If she calls and tells what happened, what is the worst that could happen? Could I lose my job, or will I get written up?
