Pick n pay Bullies

So a black security male worker who works in table bay mall had bought some items at pick n pay table bay mall and the cashier rang it up to R26. The guy asked three times is the cashier sure and the supervisor said yes. The guy went on and paid the R26 and left. Few days later the manager is at this male securitys work place threatening him because the cashier made a mistake and charged him R26 instead of R1026. The manager was very unprofessional firstly. Going to his place of work like a **** loan shark of some sort. This male security did not ***** anything. He did not commit any sort of *****. He just paid what the cashier told him to pay and now he is being threatened because of a mistake that pick n pay cashier AND SUPERVISOR made. Today I saw the manager shouting at this guys work place and that is totally unacceptable. If the cashier made a mistake it's understandable because humans make mistakes. But it is not the fault of the security guy and now he is being threatened with legal action. If this was any other customer I'm sure they would handle it differently. I've taken the security guys number because he is afraid he will lose his job now so I will follow up with him daily. What Bullies Pick n pay staff are. They are really taking advantage that this man is a security because I'm 100% sure, if this man even looked like he could afford lawyers they wouldn't treat him with no respect and like a common ********. This man is a customer too!!!!
