I'm going to tell you a story.
Mrs. W. ordered four gift boxes of cheese from the Cheshire Cheese Company, each box containing four x 200gm truckles of posh cheese. One box was for us and the other three as gifts for friends who we know are posh cheese fans. Each box was just under £20, so with delivery costs it was going to be over £80.
We've ordered a lot of stuff on-line for Christmas and have been receiving deliveries almost daily. Last week we found we'd had some deliveries left in the porch, one of which was unexpectedly rather large. On inspection I saw it was from the Cheshire Cheese Company. At that time I didn't know Mrs. W. had ordered anything from them so I called her to ask what she'd ordered. She told me what it should be, but it looked like a very big box for just 4 boxes of 4 truckles. I know that sometimes we get deliveries with big-ish boxes loads of filler, so I thought this might be the case with the cheese ....... until I tried to lift it and it was very heavy.
When we opened it, it contained 16 boxes rather than 4. I asked Mrs. W. to check the order to make sure she'd not ordered 16 boxes rather than 16 truckles, but the order was correct and she'd only been charged for 4 boxes. I'm guessing that someone at the company had mistaken 16 truckles for 16 boxes and no-one had noticed the error.
We did consider just keeping it, but it's an awful lot of cheese for us to store and dispose of, and a loss of over £240 to the company, so we did the right thing and mailed to tell them about it. They mailed back to ask us to send a scan of the delivery note, which did show 16 x 4 truckles. So they said they would like the surplus back, but we said they'd need to arrange a courier to collect it from home as we didn't want to have to take it to a collection point. They agreed to this ..... and we've heard nothing further from them for over a week, so it looks like the local food bank is going to get a donation of posh cheese.
