I picked out a bag at a charity shop yesterday. I wanted to try on some clothes in the changing room, so I gave the bag on the counter and told the person behind the counter that I was going to take the bag but wanted to try on some clothes first and then maybe pay for everything together if the clothes fitted.
While I was in the changing room the manager seemingly had come in and saw the bag. Having been told it was being held for the customer in the changing room, she told the assistant that the price was too low on tag (3.99) and to whack another fiver on it.
When I came out of the changing room the assistant informed me of the revised price. I felt a little bit stung.
