Usage examples of "luncheonettes".

Remo said, sitting back naked in the mayor's tan leather chair, looking out over a street filled with happy Puerto Ricans, happy luncheonettes and happy record stores.

In Gainesville I thought I'd sleep by the railroad tracks awhile but they were about a mile away and just as I thought of sleeping in the yard a local crew came out to switch and saw me, so I retired to an empty lot by the tracks, but the cop car kept circling around using its spot (had probably heard of me from the railroad men, probably not) so I gave it up, mosquitoes anyway, and went back to town and stood waiting for a ride in the bright lights by the luncheonettes of downtown, the cops seeing me plainly and therefore not searching for me or worrying about me.
