Unfairly treated

I've been standing on the que to by medication. A gentleman by the name of Patrick Moleko from medirite Dobsonville said we must stand in a que to speed up the process. Later on a lady just came and budged into the que. When I ask what the reason. He said I don't have to explain but when 6our chance come I will. So he just broke his own rules and I was so a ashed with such experience.
