Work Story Time: It was literally my second day of my new job on tills, and a customer came to me with a lot of items after scanning everything
I asked her if she had a loyalty card, and she said no and went to pay for her item.
She taped the card machine slightly so the machine message was for her to retap. Instead, she pulled away fast and said,
"Oh, I do have a card, actually." I knew before if I needed to go back to the scanning page. I could just press cancel, and I could add her card on. So I clicked cancel, and the machine froze and still wanted her to tape her card.
I told her I wouldn't be able to add her card on, and she said. I remember you tills do this before. So I asked the woman who was supposed to be training me how to fix it, and she told the customer that because she had already tapped the machine it will need to be restarted and I can take her to a different till.
Now I didn't know you could just bring up a already started transaction on a different till because I hadn't been taught that yet so I asked the lady for her husband to bring to stuff back and she got really annoyed with me and told me I had a very simple job and I should know how to operate a till without messing it up so much.
I was very panicked at this point, and I struggled to speak when I'm panicked, so the customer just kept going on about how I should know better. My other co-worker took over for me and helped the customer whilst I waited by the help desk for her to leave.
As she was leaving, I started to cry, and she and her husband looked over to me, and we obviously talked about me, so I cried more and a coworker had to make sure I was okay.
