The operator of the major sushi restaurant chain Sushiro has said it will temporarily limit the use of conveyor belts to specifically ordered food after a customer was found to have misused and licked unused cups and sushi.

Akindo Sushiro Co. said in a press release Friday that customers will be asked to order food on a touch screen panel instead of taking ready-made food served on plates that travel on conveyor belts past numerous diners.

The move comes after videos of unhygienic behavior by customers at various restaurants racked up millions of views online, leading Akindo Sushiro to file a complaint against a customer earlier this week.
