After waiting in the drive thru for 15 minutes we finally get to the window just to be told that if I want a simple iced coffee which takes nothing to make that we have to come inside and order because it's too busy. So what is the point of a drive thru? We have to come inside for anything we order apparently. Waste of my time and completely unhappy with the service of this location. Who came up with the idea of not serving certain drinks thru the drive thru. That's poor management skills.
