The silver lining is I can nip inside to the almost empty coffee shop and leave with my order before two cars have been served. No idea why these people would rather sit in their car for twenty minutes than walk for twenty seconds.
Waiting time is shorter and I don't have to keep idling the car ( or turning it off and on again) before I can order.
I'm used to running inside because I ride a motorcycle a lot, and you're right the wait is almost always shorter inside the building. It's fun to see the same cars sitting in the line when you leave.
Ahh but you can't ever be part of a pretentious and pointless pay it forward chain, where suburbanites of the same financial status pay roughly for someone else what they would have paid for their own drinks
