Thks Perlogirl28. Maybe I lack imagination but I really cannot see what bad experience may have occurred. Bag was paid for and boxed. All I needed was for the store to keep hold of it, for 2h max, while I was going to another of their local stores, to purchase more of their products. Anyway, I'm over it now. Not a massive deal just a small disappointment.
it could have been taken by another client on purpose or by accident , accidentally sold again etc. stuff happens in busy stores with lots of SAs
