(We have some yogurt and tomato paste which come in two packs. A customer will often come up with one tub, the one which will have no barcode on it, and we have to go find the other one in the pair.)
Me: “Oh, this is just a single. Do you have the other half?”
Customer: “No, it was just like this on the shelf.”
Me: “Ok, well these come in two packs. Did you see the other one of the shelf?”
Customer: “Yeah, I did, I’ll just go get it.”
(The customer goes and gets the other half.)
Customer’s Child: “Mummy, where did you go?”
Customer: “I had to go get the other half of this.”
Customer’s Child: “But didn’t you just break that in half?”
Customer: “No I didn’t.”
Customer’s Child: “Yes you did.”
Customer: “No, it was just like this.”
Customer’s Child: “Yes you did! I remember you saying you only need one, why should you pay for two? And then you broke it off.”
Customer: “Alright, alright, here’s some money. Why don’t you go and get a toy out of the vending machine?”
