False accusations

I was shopping for some cold drinks . I couldn't decide on a flavour so I decided to consulate some friends about the flavour only to be dragged out of the store into the store room by a security guard who searched me looking for "stock",only to find that he had falsely accused me. He didn't even apologise for the harassment instead him and the manager argued that the store was thiers and they could do whatever they please to their customers. They also threatened to call the police if we didn't comply with their demands.
