Maybe some enterprising types would consider a drive-thru like McDonald's ....mmm ... no, on second thought that would get people into trouble. Also, the image of some clown giving me a handjob is just kind of soul-destroying and is the stuff of nightmares...
What about a Mr. Lube type of drive-thru?
A coffee and a paper while you wait.
When it's your turn, you drive into a private bay.
Lights dim, mood lighting snaps on and sexy music gently grinds out of a surround system.
A projection screen drops down in front to play the porn du jour
An attendant slides into the passenger's seat with a smile and lists the options & monthly specials.
(Xtra $$ for windshield cleaning)
Post service run through quality control checks (fly closed, belt buckle done-up, etc)
15 min guaranteed in/out service.
Loyalty programs and promotions.
A discrete windshield sticker to remind you of your next appointment.
Holy frig, that would be popular on Saturday morning errands!
