Bad Attitude in native language

I was at OR Tambo International on an early morning flight and had decided to get breakfast at wimpy. <br> <br> The menu above the ordering counter, showed the individual prices for sandwiches, upon which I ordered a cheese sandwich. A few minutes later I glanced at my till slip and realized that my order had included chips with my sandwich. I spoke to the waitress on duty and explained that I did not want any chips, and has ordered based on the menu and was not asked weather I wanted chips or not.<br> <br> After a bit of hesitation she proceeded to call individuals to get the authorization to change my order. In the process she was mocking me explaining to her colleagues in her native language 'That this customer is making fuss, she placed an order and now she wants to change it'. She had assumed that I did not understand zulu since I was from another race. This explanation was given to all of her colleagues who were involved, and then when attending back to me, proceeded to smile and talk in a respectable manner. <br> <br> How many customers have been unknowingly treated in this way? Customer service does not mean take advantage of a persons lack of understanding a native language.
