Complaining about customer service , false accusations

Went to buy few items for the week at the local checkers eco boulevard in Centurion. After paying at door the security request I should be searched, when I ask him why, he told me another customer says saw me *****ing something. I never felt so humiliated. I would like to believe this shop has cameras and they wouldn't just accuse people of *****ing which themselves didn't see but heard from another customer.
