Sorry not an AIBU, but just in case the owner is a mumsnetter...
I went shopping just after lunch and noticed a folded up buggy at the back of a car parking space in my local Asda (don't want to be too specific as it could out me). It looked like the owner had forgotten to put it in the boot after dealing with shopping / children.
It was a black one (I'm sorry I can't give more details, I'm not a parent so to me it is just a black buggy!).
Anyway, if it was yours, I took it to customer services in the hope the person would go back for it, I didn't want to just leave it as it looked expensive.
If you hear if anyone who forgot theirs whilst shopping, please pass this message on and get them to check customer services.
