Uber eats fight our foreign business trauma

Today on the 7th September I went to Wimpy in Pietermaritzburg at Woodburn, I initially wanted to go withdraw money at the ATM and go back home but I saw wimpy store I got excited and I went in and ordered a caffe late and a light meal. This was my first time at Woodburn Wimpy and I was looking forward to having a peaceful morning. Little did I know a few minutes later two guys walked in from uber eats to collect their order and while they were waiting for their collection another uber eats guy also came in to collect. The two guys started to push this guy making a scene at the restaurant that he was a foreigner and why are they working with foreigners. This continued for an hour they were threatening the staff, shouting, saying that next time they will come with guns in the store and shot at everyone. One of the staff member called for help and later the security company come and they was an altercation and they refused to leave the store customers were rushing out of the restaurant, I paid asked for a take out cause I could not stand to watch this any longer. I was really traumatized to the point that I could not even eat my food, I am mostly afraid for the staff members that had to go through such a horrible experience and judging from those guys comments they are going to come back to make sure that foreigners are out of business. Maybe Wimpy should consider having a security for our safety and the staff.
