Bad service

Dear McDonald's am not happy about how they treat us at Jewel City. Yesterday I was a customer for the day, then I went out and came back later for toilet I wanted to pee. That fat yellow boned lady (didnt get her name correctly) who works at McCafe chased me out and told me the toilet is only for customers as I wasn't a customer I even explained to her that I am a customer and I was even during the day she said it doesn't matter cabana nje. Because she didn't see me buying now she telling me to go out. For her knowledge I am a customer for McDonald's not only for Jewel City but for all McD. That day I even bought 2 meals Big Mac and Quater pounder but she has a nerve to tell me it's ònly for customers. Now I will think twice even to go there to buy.
