Exhausted…

So, I’m sitting in line at the Dedham Starbucks drive-thru this morning and I notice this:

This building is fairly new… maybe 2 years old. Notice all the paint peeling in the corner, (the rest of the building is doing fine). If the idling exhaust from cars (who are in line for a only a few minutes) is doing this to the paint, what the hell is it doing to the environment and to the drive-thru staff??
