Video footage of a woman verbally attacking a fellow customer at a Clicks pharmacy in Durban has been circulated on social media.The video shows the woman in a heated confrontation with another shopper at the store's dispensary counter."Why are you laughing? What's so funny?" the woman asked."Don't get yourself involved in things that got (sic) nothing to do with you," she says as she approaches the woman.Although it is unclear what started the altercation, the video appears to show the shopper who was verbally attacked sticking up for a member of staff. She can be heard saying "she's just doing her job" before the woman in question launches her verbal assault.Clicks Group spokesperson Susann Caminada said they were aware of the video and were looking into it."We are aware of the video and can confirm that an altercation took place between two customers at a Clicks store," she told News24."We are busy investigating the matter."The unidentified woman goes on to say: "I will give you a fucking backhand and you fly out of here."She then threatens to slap the customer and places her hand close to her face."That's why Julius must fucking take the land," she adds before stepping away.
