Japan's conveyor belt sushi restaurants are struggling to regain the trust of diners, after the industry took a licking from one customer, whose viral videos of him defiling utensils and sushi with his saliva have earned him descriptions ranging from "nuisance" to "sushi terrorist."
The Japanese public's reaction suggests it's a brazen assault on two things of which Japanese are very proud, their sushi and their manners.
With a furtive glance and an impish grin, the young man in the video licks the rim of a teacup before returning it to a stack in front of his seat, where unsuspecting customers may pick it up. He also licks soy sauce bottles and smears his just-licked fingers on pieces of sushi making their rounds of the conveyor belt.
