I stopped by Dunkin' Donuts this morning to get coffee.  The drive-thru was extremely busy and there were cars spilling out into the adjacent parking lot causing a bit of traffic to back-up and be diverted.

I pulled up to the front of the store, said “Hi" to the woman cleaning the windows on my way in, took my order (no line) from the very tall man and even got a “Have a nice day” from him as well.

Was back on the road with my hot coffee in no time.  Not sure why more people don’t do this.
