I bought a women's blouse, and it was on a hanger labelled Medium (12 - 14) At home, I found it was a size 10. I returned it and asked to swap it for something else in the larger size. I would have said there was no problem, except that I suddenly got a ticking off! I provided the till receipt, the bank receipt and the item freshly washed (not something you would do in a store but nice for charity shop clothes where they often just steam them). I didn't expect to get into trouble, something to do with the ticket - however, that had the wrong size on it, they needed to write out a new one in any case. It's not much of an issue, but that kind of thing just makes me go to a different charity shop another time.
