Lack of Management training

My review is not based on the meal I had received as this was delicious as always, however the reason for my "1 star" is that the management staff are poorly trained or seem to have not received proper management training.

On Sunday, 06.03.2022 I had visited the Nandos stores at Pavilion Durban. There was a misunderstanding between myself and another patron (the full story will be explained if I get a call back from Nandos Head Office). However, this man was becoming terribly vulgar and had verbally assaulted me. The cashier had proceeded to call a lady who i think is the store manager. She stood there whilst this man continued to use vulgarity on me and she did not even seem to care. Surely the management team should be trained not only to handle their staff but also be trained in "Conflict Management or Conflict Resolution" for situations like this.
