Nearly vomitted after eating pink burger

I was diriving from Joburg to Klerksdorp. I was with my 3 year old daughter. We were starving as it was 12:00 midday and we hadnt eaten since morning.In short, just to get a menu took about 10 minutes before one of the two waiters that I had asked could bring it. Then it took almost half an hour for the food to come. The couple seated next to me found me and their buffalo wings camelong before my food. When the food came, I started eating. After 2 bites, I noticed that the burger was pink raw inside. I then took a while to find the waiter. He said he will prepare another one. As I was not going to wait another 30 minutes, I told him that I did not have the time to wait again. After disappearingf for someitme, he came with a receipt and said I should pay for the other burger (my child's) and drinks. I regret paying that money without a fight. I then found my way to the manager who looked speachless and could just say sorry (not even a genuine one). The Spurs I know will even give courtesy to give something on the house. I only ate at 7 that evening as there was loadshedding when I arrived in Klerksdorp All because of that nonsense Spur! I am still angry even now.
