Fast food restaurants near us usually use bicycles or electric bicycles to deliver meals. I think it's inconvenient and convenient, because convenience means don't be afraid if there is a traffic jam, because you can wear it around! It is inconvenient that food can't be delivered from a long distance, so some fast food restaurants with good business have minivans to deliver food, but they rarely deliver food. Because it takes a lot of oil to send a few dollars of box lunch, it is not cost-effective, so big hotels with takeout will use minivans to deliver meals. (They are all sent by some factories to employees, and there are at least fifty or sixty boxes of lunch boxes).
