Too rude foreigners, they must go

Today 05 July I was driving at Edenvale looking for Makro and got lost, then I went to Van Riebeek and Herman Caltex petrol station - and found a very Zimbabwean attendance who used heavy vulgar language to me. Now I fully understand and agree with the South Africans who say these people must leave our country. Then another attendance joined too, and I heard that the same petrol station is collapsing - it really make sense because their petrol attendance are extremely rude and angry or maybe their thinking is back home. They really need to leave whether there isn't electricity and water in their country, who will fix their place when they fled to other places and nobody wants them. Most countries kick them out because they misbehave and too rude. That Caltex will eventually go down the drain because of such rude foreigners.
