In a NY Times article 8/8/12, interviewing Art Oehlke, owner of the 530 antique shop in Lorain, OH (echoes of "Darling Lorain" by Paul Simon here):

Mr. Oehlke did not say how much the shop makes. But a clue, he said, is in the thermostat on the wall near the cash register, which showed 45 degrees. If the store were more profitable, he said, it would be warmer. But he preferred to see the bright side.

"It's got an advantage," he said. "If I have to go somewhere, I already have my coat on."
