So, in my department, we sell what’s known as cold patch. It’s a bag of asphalt patch that’s meant to go on the asphalt at ambient temperature. Really useful for DIY fixes of potholes in your driveway, or small potholes in the road.
Customer (on the phone): Hey, what’s the coverage on a single bag of your cold patch?

Customer: Oh… Well… Um… hangs up
