An old fellow I used to fish with bought a few thousand worms every spring, and kept them in an old bathtub in his barn. You could probably fill a pickup truck with the yellow perch and bluegills we caught with those bathtub worms. He would toss coffee grounds in there, but nothing that would smell.
Like most normal people, he never heard of a "compost heap", and would have laughed at anyone who tried to explain.
