A dream about Walmart

I dreamed this several days ago and I still remember it, probably because I've told it at work numerous times.

I dreamed I was at Walmart, checking out a customer. I was scanning a ham and trying to scan the serial number, but somehow I accidentally scanned the serial number on some pictures from the photo lab instead. I got the order all mixed up and finally just decided to abort the whole transaction and start over. I waited and waited for Sandy, who was the other CSM, to approve it. I waited about ten minutes, and the customer was getting quite upset. I kept paging on the walkie, "Sandy, can you please override me?" but Sandy wouldn't answer. Finally I paged management and told them that the CSM wouldn't override me. Rosie answered and said, "Why don't you call out to Garden Center and see if they have an extra handheld?"

I decided that instead of calling out there, I'd just go out there since I wasn't that far away. So I left my customer and ran out to Garden Center, and there was Sandy, standing right there with a handheld on her wrist! "Sandy!" I said. "Why didn't you override me?" Sandy looked down at her wrist and said, "Oh, my handheld went down."

(If you know Sandy, this dream is a lot funnier and makes a lot more sense.)
