Non preppers / Doomers. What's one small thing you're prepped for?

I keep a few things (museli bars, water, blankets first aid kit) in the car in case of getting stuck somewhere or needing basics suddenly.

At home I keep 'minimum levels' of things we use often, in case of a power outage or just so if anything were to happen we could get by for a couple of weeks. We are limited by space and try to keep organised.
