What did we ever do before the drive-through window opened up? We got out of our cars and went inside to order food and drink. It's quite convenient especially when it's raining, snowing or temps are cold. The last thing we want to do is get out the car. If the drive-through line is long, I will park and go inside. It saves on gas and the environment by not having the car idle in the long drive-through line. So eco-friendly!
