We’ve come to Marrakech, the swirling heart of Morocco at the base of the Atlas Mountains, at the urging of Sam’s friend Mohamed. The two met when Sam became entranced with a lamp that hung in the window of Mohamed’s New York shop, which sells all things Moroccan. Sam went in for a closer look. The two got to talking—and then haggling. “Make me an offer, Sam,” Mohamed told him. Sam bounced all over the shop, touching everything as he shouted out prices. “He reminds me of myself when I was his age,” Mohamed told me. “With a little practice he could become a good haggler.”
