Right, first post on AIBU
On Tuesday I went shopping for clothes for two events I've got coming up, I had my 5 month old DD with me in a carrier so wasn't able to try anything on so I bought a few things and tried them on at home.
One of the items was a dress, I'm a bridesmaid at my friend's wedding in July, it is very informal and she has asked us to wear floral maxi dresses. I was happy with the dress when I tried it on and sent her a link to it and she likes it too, so great - all sorted.
Yesterday I wrote an email to the other bridesmaid and sent a link to the dress again and noticed it had been reduced from £39.50 to £25.00. So I thought as I had lots of stuff to take back I'd return the dress too and then get it at the sale price.
I went into the shop and explained to the assistant that i wanted to return some items and about the dress and she said fine about the returns but not about returning the dress and rebuying it as this was fraud! 
I really don't see how this transaction could be considered fraudulent in anyway - yes I can see how it is a bit cheeky and annoying for the shop but not that I was asking to do anything illegal.
So I said fine I'll return the dress then I got my DH to come over and asked him to go and get another dress off the rack and buy it. The sales assisatnt was not happy at all and said she would have to get another member of staff to serve him. Then followed lots of tutting and 'we really shouldn't be doing this...' etc.
We were made to feel like we were committing a crime,
So..... AIBU or was she?
