We always keep a stash of cash hidden in our cars. Comes in handy when you're low on gas or food, and you don't have enough money in your pockets. Or plain forget to carry your wallet, as I have done a couple times when switching jackets.
We always keep a decent amount of cash stashed here at home. We have done that for decades. You never know when an emergency might arise in which immediate cash is needed. And with the current state of the world those “sudden emergencies” seem more probable than ever.
