The Lou Gehrig of Beer Guys

Before hawking, Duvalsaint, who is thirty-four, worked at HSBC in New York, in platform sales. In 2017, while visiting his parents near Miami, he wanted to catch the M.L.B. All-Star Game but balked at the ticket prices. Instead, he responded to a Craigslist ad for short-term help. “I don’t remember my first hot dog sold, it was so quick,” he said. “I made it about ten feet before I got swarmed.” The pitchman Anthony Sullivan, from OxiClean’s infomercials, also happened to be at the game. He was walking around on the concourse and saw me selling,” Duvalsaint said. “He said, ‘You’ve got a great future in sales!’ He even came into the seats and said, ‘Let’s push these hot dogs!’ ”
