In Italy, @sneakypete , they are even telling people not to use "vending machines", that was covered in one thread. Can one imagine, you want to buy a coke, chips and that. At the least, hit the button with a stick, napkin or something. Pretty alarming. Yes, and my understanding is that money gets real dirty.
@TomSea Tom, in my book, "EMERGENCIES HAPPEN! BE PREPARED NOW!",
I suggest keeping a number of small bills, such as $1 dollar bills (more of them than any other), $2 dollar bills and some $5 dollar bills, and change such as 25 cent coins, at home always. If banks close, credit cards are a piece of plastic no one wants, but the cash will help you get what you need, even if that is paying someone for a service you need done around your house.
With banks down, you can pay cash for groceries for a while - until the store closes due to no trucks bringing food.
The food chain is this:
A truck goes to a warehouse to pick up a load of whatever, such as food we are talking about.
Before the truck can leave, the money for delivering the load has to be paid right then or the truck does not leave. This exchange of money between the two businesses, goes through the internet, the bank transaction is done and the truck can leave. The truck will not leave to deliver the goods if this money transaction doesn't happen. Food delivery stops.
