The Worst Shuttle Service Ever.

It was the first and last using it, it was the worst experience ever. It was 3 us traveling with city bug, we get to OR Tambo Airport the 2 guys with me rush to the toilet. I alerted the driver since they were not feeling well, the driver left them in the airport while I ask him to wait for 10 minutes. Only to find out it was not even time yet. We stopped also in Middleburg, I rushed to the bus but we waited for a white couple and 2 white boys. Then I asked why wait for them but since we must adhered to the schedule, only to find out since the driver is white we will wait for white people but my African colleagues we left them behind. They had to take a later bus and pay full price. Never ever, I thought I'm supporting my hometown business but it's full of ******. Never Again.
