STILLWATER, Minn. — It’s a Monday afternoon and there are only a handful of people hanging around inside the Oasis Café in Stillwater.

There’s a waitress and a single cook, along with a guy in a back room washing dishes. Only a few of the retro-styled booths with their pale green cushions are being used, and there’s no one sitting in on the matching green stools that line the stainless steel wrap-around countertop taking up most of the space in the main dining room in the 1950s-style diner.

Doris Day is singing “Dream a Little Dream of Me,” on the radio overhead, though it is partially drowned out by the sizzling of hamburgers on the grill in the open-air kitchen behind the counter.
