Mochachos poor food quality& lack of cashier skill

I went to Mochachos Klerksdorp and ordered 2 x Chicken Burger Meals I had to repeat myself as the cashier struggled, he told me it would take 20-30 minutes, understandable for good quality food. We sat down and waited for our takeaway meals, it was brought to us by a waiter. I had to go back to the cashier for our soft drinks as they did not ask us. Once I came to the cashier he looked at me as if I'm crazy when I asked for my drink of choice I made sure if we get a cool drink with the meal as it felt I might be wrong the way he treated me. Once I got in the car I opened my box and instantly saw the bad quality, The bun where a little old the chicken fillet didn't cover my bun and was about 5mm thick which is a total ripoff and clearly not as it's advertised. The garnish was minor and there where little to no sauce (mayonnaise) on the burger, the chips were fresh and hot but slightly over seasoned but was the best part of the meal. I was at a few other Mochachos branches and this is by far the worst quality and service I got!
