It is amazing what some morons will try to shoehorn through a drive through. Last year some idiot tried to snake a Suburban pulling a double axel featherlite trailer through a Chick Fil A near me. I really wanted breakfast there when I drove by but I could tell that was a cluster in the making and kept on moving.
A friend of mine drove a horse trailer under a drive-thru awning/roof (decades ago .. old style sort of thing). Fortunately, she stopped soon enough that she could back out without ripping the top off the trailer or bringing down the drive-thru roof - noise was pretty bad, though.
