Why yes I would rather sit in my comfy padded chair in the AC where I can listen to my own music and charge my cell phone rather than sitting on a metal chair listening to 20 other people's conversations in 100 degree weather.
There are many arguments against drive-thru restaurants. This is a stupid ass one.
The quality of my car seats and its various other comforts vastly exceeds the quality and convenience of most restaurants, because it can drive me to anywhere the roads lead to and it doesn't have all those other stinky people in it.
Yeah I'm going with option #1 but only if I didn't already bring my own coffee from home, which I'd normally do because it's better and cheaper than what the restaurant has too.
