Unless you have been taught at a young age that cooking is something valuable, I've found out that a lot of adults run from it like hell. When covid hit, I expected people to start being reasonable with their budget (and health) and reckoned that food delivery services would have a rough time surviving.
Turns out, people started ordering food for home a lot more, even though they now had the time as well as the incentive to save money due to the uncertainty.
