Accused me of *****ing

I'm so embarrassed. I went to Woolworths East Gate to return an item of clothing I received as a gift. As it was a single item I carried it into the store in no bag past the security to customer service (I even asked where it was). When it was my turn in line I was asked by the teller where my bag is that I am returning the item with. I explained I had non and had a single item, she then imp**** I had ****** the item and called her manager who was went straight to security to \check"that I had indeed not **** and ****** the item. After that the customer next to started giving me dirty looks like I was guilty of *****ing. Eventually the item was returned and I left the store embarrassed and ready not to retune to the East Gate branch ever again! """
