Rude Staff at Macdonalds Mayville Pretoria West

I was at Macdonalds Mayville in Pretoria West this morning around 7.15am. I had been driving for an hour and a half from Joburg South and wanted to use the loo and then order breakfast. I was stopped by the cleaner, Ralisile, and told that I need to order before she allows me to use the bathroom. I was extremely pressed but she was rude and extremely persistent. I find this very offensive and unprofessional. If I use the loo first or order first should be my own choice. This behavior is totally unacceptable.
