Have you tried paying cash at a food truck recently? I've yet to find one that doesn't accept cash, even in a major US city close to tech campuses. With the exception of a few small restaurants, the local self-operated car wash that kept getting robbed after hours, and a few farmer's markets (usually also at incredibly inconvenient times), I've yet to find a place that doesn't take cash. I've been to multiple restaurants in the past month that only accept cash, though.
