Chadwick’s PM Mart sold everything from salami to comic books. Most customers shopped a‚er 5 p.m., spending their money, whatever its source, on beer, wine, and underbird. e tra¨c generally slowed a‚er 2 a.m. Chester Chadwick was thinking of closing his store from 3 a.m. to 6 a.m. due to the lack of business. But his clerk’s minimum wage could be o°set by one or two sales during that shi‚. So far, he managed to cover the costs of remaining open. But one customer at 4 a.m. on a Sunday morning in October changed his mind.
