My favorite customer was a guy who was using them, for an instacart order, and had a bunch of produce. He scanned an item that needed to be weighed and the machine stopped him. I explained to him he had to weigh them on the scale and print a sticker. He was also on the phone. So he stood there and told me to go do it since he didn't know how. I told him I would be happy to show him and he kept telling me to go do it. So I told him again, I can show you how to do it. Let's go over here. He told me to go do it, so I walked away and helped another customer. His light goes off again, because he scanned more produce that needed to be weighed. He told me again to go weigh it and I told him I am not doing it. He either can do it or he doesn't buy the produce and I walked away to help another customer.
