Horrible service and long waiting time

This store staff is rodiculous! All they care about is the drive through and not customers that walk in store. I waited for more than 20minutes for my order. And this ia not the first time. When one asks and demands service we are given attitude and not even an apology. There's more than 10 staff members right now and all of them are at the back attending to drive through orders. This is mcdonalds at the protea glen mall
