Hoping to convert his daily constitutional into cash, a correspondent recently amassed more than a hundred sweatcoins by walking around New York, and then investigated what he could reap from his labors. At the Gap, when a clerk ringing up the correspondent’s purchase asked, “Do you have a Gap card?,” the correspondent said, “No, but I have sweatcoin.” The clerk furrowed his brow and demanded legitimate currency. A cashier at Astor Place Hairstylists was impressed by the concept, when it was explained to him (“Sounds like a million-dollar idea”), but was unwilling to accept sweatcoins as payment for a haircut.
