They’re usually called bikini baristas and its a woman in a bikini or lingerie who makes coffee. Some got busted years back for doing handies.

I have never actually patronized one but there’s a few in my area, mostly in gas station parking lots. The operations can be pretty fucking rough.

I always cringe when I see the poor girl throwing on a bathrobe to cart the wastewater across the lot to the gas station slop drain since there’s no internal plumbing in her road facing booth.
