So sorry to hear about your aunt's purse being stolen. The same happened to my husband last year in the same place, fortunately, he realised what was happening and they threw the money on the floor! We asked the owners of the shop to see if it was caught on camera............... it was!! We went to the police and reported it, they apparently went to the shop to view the theft, so maybe it would be a good idea to ask the shop owners?
DO report it though
