This might not seem like much but it's hard to overstate how sophisticated your country's logistics and infrastructure needs to be for this to even be possible. It's actually insane when you think about it: when you take the fast-speed train in China, you can order takeaway from restaurants in the city of the train's next stop and it'll be brought to you to your seat. So much can go wrong with this that you need every single piece - from the rail network to the corner noodle shop to the 5G tower to the delivery scooter - operating with the precision of an orchestra where no one can miss a single beat. Really illustrative of the insane level of systemic sophistication that China has achieved. For one thing, most countries can't even manage to have trains run on time.
