The Sydney Morning Herald reported that new legislation had been proposed that would require operators of yum cha trolley carts (as seen in Chinese restaurants) to obtain a license. The legislation had been proposed due to "dangerous trolley usage in yum-cha eateries." An expert noted: "There's been a lot of problem with dumpling accidents particularly. Dumplings retain their heat for quite some time. You get one of those in your lap and it can be extremely painful." Under the new rules, operators of the food carts would first have to complete an instructional course, and then would "carry a small 'L' plate on their carts for six months before being granted full licences."
