We tried to go through the drive-thru after picking someone up from the airport. It was about 1:10 am, so it was one of the only places open. We sat at the speaker for 5 minutes before yelling and whistling into the speaker to see if anyone was even there. At that point, an employee came outside through a side door to tell us that the cashier was in the restroom and they were going to take 10 minutes. He has a headset on, so I can't fathom any reason he couldn't have taken our order. Like really?? You'd let your only order-taker spend a quarter of an hour in the restroom and have NO backup? Just stupid. This place has 2 stars for a reason.
