Just went to the local Speedway to buy gas. There were CASH ONLY signs on all the pumps because of the internet crash. Happily there was a working ATM inside and I was able get some cash and pay. Even the attached Dunkin Donuts was CASH ONLY. We really have set up a system where much of the modern world can be shut down all at once.
@chrisaldrich Maybe you should add some mechanical cash registers to your collection.
