ROC had a problem, people didn't order in food, because they believed that by the time it arrived it was cold. Not all deliveries suffered from delivering cold foods, and ROC never did, but how does one tell people they deliver hot food? Easy - install a fire on the delivery-scooters. Eye-catching in traffic as it turned the delivery-men into living advertising billboards on the road.
I like the idea. I also like how totally verboten this "simple" scooter install would be in Sweden, it's breaking all sorts of rules.
