KFC Watergate

We always thought KFC Watergate was top class until yesterday,my wife stood in the line to place an order at the self-help machine,i needed to pee so i asked a guy working at kfc to open the toilet,he told me he need to see my order slip first,i explained to him that my wife are in line to place an order,he didn't wanna give in , I asked to speak to the manager,she didn't wanted to assist me,at Watergate there are a public toilet,why would i want to **** KFC to use their toilet? Pathetic
