If it demanded cash and suggested visiting your local Citibank Branch or Citibank In Network ATM that clearly would also be an equally random and meaningless data point, totally not trying to make Citibank look bad or anything.
If "cash" was a random form of currency that the pizza parlor had statistically never heard of and had literally no idea on how to acquire, then providing an address for a specific ATM would be pretty random and meaningless, yes. Would you expect an extortion letter to say "If you don't pay me one bitcoin, I'm gonna screw with your business. I'd tell you where you can find a bitcoin, but I don't want this extortionary attempt to slander the name of legitimate businesses who are trying to increase the adoption rate and accessibility of this exciting new crypto-currency"?
