Drive through is pretty fast.
I came with my friends, just wanting a few sodas. Drove up, ordered 2 diet pepsis and an unsweetened ice tea with extra ice. They didn't repeat the order, so I was kinda unsure if they got my order right. Sure enough, they gave me a sweetened tea (lacking ice). Of course I didn't notice until we had left the area so, there was no point in going back. Kinda disappointed that they can't get an order of 3 soft drinks correct.
