VERY IRATE CUSTOMER

Received the worst service ever at a Mcdonalds restaurant in Pretoria Gateway. Ordered a Mcflurry and a chili cheese double, the Mcflurry was just wack, it was not even mixed/stirred the oreo was floating on top. Not sure if the slip is clear and again if a Regular meal and a Medium meal is the same thing because they cost the same amount. When I wanted to query that I was told “to leave” because they doing me a favour apparently. I work in retail myself and I know for a fact that You DON’T tell a customer that you doing them a favour. I understand that it was closing time but I have never felt so disrespected in my entire life.
