A tissue box that you can drive seems stupid at first, but it could be a hot product given our current state of hysteria over germs. I say quarantine the sick and deploy RC vehicles to handle it.
You can already deliver tissues, so all you need is an RC Cooler for drinks and a RC Ramen cart for soup. If this isn't enough to calm your fears about possible contamination, there are always more extreme methods you can employ. [Rakuten via Crunchgear]
