I've stopped here for coffee a few times, and each time I go through the drive-through. Each time, my order gets messed up in some way. The coffee itself, however, typically makes up for everything else.
The drive-through speaker is definitely messed up. It's hard to hear the employees, and I'm guessing it's hard for them to hear orders. That, or DonutTron 2000 keeps screwing up my order. Stupid robots.
