puffenstuff - I found the same when I lived in Jamaica and also in Italy. I was astonished, insulted and all in a tizzy the first time I was given a problem returning something in Jamaica. I mean to tell you - I was OUTRAGED!
I had a lot of issues there at first because I didn't understand cultural differences. I thought it was clear I was being discriminated against. LOL - now I know they DID indeed think I was a crazy woman "from foreign" as they said, but the anti-return thing was not personal.
This is one thing I do like about America - you can return virtually anything! Even bathing suits and lingerie! Wow!
