I messed up bad my first time on register
today was my first day on register at homegoods. A woman came and said she wanted to do two transactions. she was buying a bag full of a boxed food items. we were making good conversation. I pushed the button for her to pay. she taped the card, then looked in her cart and saw another of that item she wanted in that transaction. At this point, it was on the recipt screen but i didn't realize, i tried to cancel and clicked the x button to go back and add the item because she really wanted it on the same transaction.
I said I dont think it would work to add it, she started getting very upset and yelling at me. I was starting to tear up so I turned around to the manager behind me and he stepped in. I went to the bathroom to stop crying. I came back and they did the two separate transactions. redoing the first one.
Now that Im home, Im realizing that she did pay the first time, and I didnt give her the receipt. I was so panicked being yelled at and I did think I canceled it so I put it in the receipt box below the register. So she left paying twice for that first transaction.
Im freaking out that I messed up this bad and Im thinking about her coming back in after realizing and yelling at me again. I dont know what to tell my manager, I have tomorrow off but I think I should call? Please help i cant sleep.
