Bad Customer Service at Nandos Ruimsig

After ordering a full Chicken meal with sides, Nandos Ruimsig refused to put my relish on the side. I was told, I quote"No pap coming out of the kitchen without relish and it and it must be on top not on the side of the Pap "says the waitress Amanda" , she then called Zenzi the Manager I presumed. She walks straight to us with a very angry look that says "don't mess with me". Her first question was "What's the problem" we narrated the story and she says, well Amanda has already explained to you the procedure and that's final, therefore, if you need your relish I need your plate of Pap. We pleaded that they put it on the side she refused, eventually, we gave them our plate. I just feel that Nandos should hear what the customers needs are before forcing what we don't want. Please train your staff for Customer Service and can you not force the relish to be ontop especially when a customer requests for it.
