There's a lot of money-laundering fast food franchises. I remember a KFC in Baltimore where the skeleton crew that manned it were barely familiar with the menu, and maintained a largely empty parking lot at all times in what I would imagine to be prime chicken-flogging real estate (it was my neighborhood.)

They got a bit of unwanted attention a few years after I moved away when a junkie died in the single-occupancy bathroom and nobody noticed for three days.
