I know I shouldn't expect much from BK, but this location is ridiculous. You really shouldn't even THINK of going here during lunch. They have ONE cash register at the front of the store. Not just one OPEN register... they only have one register, usually being operated by the slowest person they employ.
The drive-through is no better. Cars are backed up into the next parking lot.
If you insist on trying to eat there, I would suggest you go inside to eat, that way, when they invariably get your order wrong, you can throw it directly at them. If you get drive-through you will end up like me, paying for a double cheeseburger only to get back to your desk and find out that they totally screwed you and only gave you a single. You will then slam your fists on your desk and start swearing and get called into your boss' office... at least that's what happened with me. YMMV
