Cash Crusaders review: Racism

It's the first time in along time and I'm stumped and would like to hear from everyone what your opinion is ...
I witnessed a Black Male employee Cash Crusaders (Durban, KwaZulu-Natal) call a Non-Black Male Customer a [censored]ing K*F*R and literally for no reason there are recordings/footages of the entire occurrence and everything was light hearted and jovial with all other staff members and he who wasn't even part of the conversation passed this comment assuming the victim wouldn't know because he spoke in Zulu little did he know.

I, the eyewitness did understand Isizulu and completely understood what he said.

Isn't this equivalently a criminal offense as it would have been should the victim have been the one to say it?

Is it fine to:
1. As an employee of a national chain store swear someone for literally no reason( while I don't generally believe this type of a story this one is on record so it isn't a one sided story)
2. Call anyone the "K" word as long as they aren't black because only a black person has the right to be offended by the derogatory and historically disgusting word?

Please feel free to express your opinion in the comments below.

The purpose of this post is to hear what and how others view the above

And if CashCrusaders Krugersdorp CashCrusaders@Calton Center Atlantis CashCrusadersCashcrusaderscash_crusaders @ samantha would like to voice their opinion on how they view the matter wherein the people who are their representatives behave towards the public.

P.S. I have the picture of the culprit but I do not believe this is the appropriate platform to expose him
