Years ago at a huge Christmas Fair at a stately home 60+ miles away.
We went round the stalls first, before going into the house to see the decorations. I bought some beautiful glasses that were quite pricey and a few baubles. The stall holder wrapped them very well and offered to keep them until we'd been around the house - she put our name on the boxes she placed them in.
We collected them and went home. I didn't open them for a few weeks, until Christmas Eve. As well as my beautiful glasses there was a matching decanter in one of the boxes. Nothing I could do then.
I phoned the stately home after Christmas was over and they said if I didn't know the name of the stall holder there was nothing they could do. I felt awful, it was very expensive. We'd paid cash for a change instead of card. I'd been saving up my expenses.
So we went back the next year. DH said I was daft but I insisted. She wasn't there. I asked at a couple of other stalls if they knew her but nobody did. So I still have it, unused.
I still think the stately home could have done more, they must have had a list of stall holders somewhere.
