doc-in-a-box
n.— «The premise behind quick, after-hours medical care is not new. Two decades ago, walk-in clinics—often referred to as doc-in-a-box—were opening in almost every city and suburb. Almost as quickly, it seems, the clinics were shuttered—victims of low profits despite their popularity with consumers.» —“Bread, milk—and a diagnosis” by Shari Roan Los Angeles Times Jan. 22, 2007.
