So I was on register and had a purchase where the guest gave 100 dollars cash. When I typed in the amount the register wasn't responding and I kept hitting the 0 and 100 appeared on screen when I hit apply payment it showed 1000. The change I owed was over 900. I called so one over to help. He went to guest service to void it. I want to make sure my register is going to be fine. I have a gut feeling I'm going to get fired.
