I've had the opposite experience. Order online food and select the toggle for no cutlery. Only to have plastic cutlery arrive because the worker layer, driver layer and app layer weren't really in sync. They're just rushing to push out orders.
So I get them having a default of not providing. I'd prefer that. Still sucks though...
Be cheered in knowing that in Japan sushi is a finger food for some, no chopsticks needed.
