This isn't intended to be a PILs bashing thread, I like my PILs, and I genuinely don't know who is BU here.
DH and I live in a terraced house on a residential street. Parking is always available on our street, but often not right outside out house.
There are two disabled parking bays marked out near our house. We aren't near shops or any other amenities, so I assume that they are there because in each case the property of the house they are outside has a blue badge and has applied to the council for a space to be created.
MIL has a blue badge because of hip problems. She can walk, but slowly and it's uncomfortable for her. She uses a stick.
When PILs visit us FIL will always park in one of the disabled bays if it is unoccupied and nearer to our house than any other space. He may be occupying that space for hours at a time.
DH and I think (and have said to him) that he shouldn't do this because the person who had the space marked out presumably needs it. FIL's view is that MIL meets the criteria for use of the space so why shouldn't he park there? If each space was intended to be only for use by one house then the scheme would have been set up that way.
AIBU or is he?
