Bad Service and Bad Attitude

I was bying a XL Coke Zero and a large strawberry milkshake from McDonalds Cape Gate Mall at 17:15. At 17:28 I still havent received my drinks. I was the only customer left in the store with orders placed after mine already taken care of. I looked at the electronic display at the back, and there was nothing written on it. asking the waitress if I could speak to the manager, she couldnt find him/her. Nomphofano then stepped forward and I explained the situation to her, asking if she could please have a look. she started walking away, i asked her if she could please take a look. while walking away, she screamed aloud at me, \its coming!". i asked her to repeat herself"
