Buying delivery is one of the few ways I have to try to support local businesses a little bit... I can give generous tips, and I can avoid being infected by putting everything I buy in the oven for a while, or buying things that I know will not pass through many fingers after being cooked.

Yes, it is a risk of infection, but one that you can calculate and do stuff to mitigate.

it’s better to have a few couriers to many people than many people mingling with many people at restaurants. It’s like logarithmic or linear versus quadratic or exponential spread.

Keeping people home is helpful.
