Caltex toti oasis

I am very disappointed with the service I received from amanzimtoti caltex Oasis. I placed an order for grilled chicken. I was told to go outside cause of the covid 19 pendemic a limited number of people had to be in store. I came back about 30 minute later and my order was being started when I complained the guy was rude. Then we had an argument, after that he moved from the other side of the counter and pushed. I am very disapointed about this .How can you move from the back of the counter and walk around and push the customer. This not acceptable at all bare in mind that there is a pendemic covid 19 and you are pushing customers
