refer
n.— «As a 20-some-year professional housecleaner, the battles I’ve had over cleaning the fridge are historic! After about 5 years, I got to the point that I could not and would not even wipe out refers anymore. I’d had phone calls, verbal abuse and request to restock refers—at my expense. I thought I’d done the bidding of the homeowner, [only] to learn I’d thrown away something akin to “precious.”» —“Tales from the land of (expired) milk and (decades-old) honey” by Greg Bushman Seattle Times (Washington) Sept. 5, 2007.
