shopping rule theory

Be sure to follow the rule before you head out.
Rule: You must post before you leave.
Yeah in a cashless society things like that can't work well. In Germany cash is king, you can't go out without. In France it is mandated that shops accept at least 2 means of payments (among cash, card, check or wire transfer), and only cash and cards have enough safety and speed that shops and restaurants want to use it.
