Very bad customer service.

I came in yesterday with my friend, as i aways come there, i enjoy the food and the margaritas. Yesterday we decided to sit by the bar with my friend and ordered margaritas, the waiter gave us snacks which was olives and dried potatoes. As we are sitting then comes a couple they literally sit next to us. I then noticed their snacks had biltong in it. Biltong, olives and dried potatoes. Which we were served by the same person, out of curiosity I called the waiter asked him why we ddnt get the biltong. lol this guy literally said to me, the biltong is offered to only “regulars” i then said but im always here. Or other branches. I asked the guy how do you track regulars here because what i know is shift changes do you guys perhaps have a loyalty card or what’s happening? Something that tracks that your a regular. Because of he ended up not knowing what to say to me. I then asked him to call his manager so they can explain to me. Mathapelo the manager was very tired rude and not in the mood to talk to us. I asked her the same question about the biltongs, she said to me “ya we give biltong to regulars” I ask her what is a regular because I come here 4-5times in a month, she said because she doesn’t know me with an attitude. I am very disappointed about the service I got yesterday, I don’t understand why are we not treated equally to be honest, that’s not how you treat your customers, and the response literally shook me. Even worse the response from the manager it was not good at all. They all don’t even have name tags. They don’t even introduce themselves.
