> There's debt being created by service or product changing hands but you just put up a sign and refuse accepting legal tender to pay that debt? Yes, but the interpretation is that you picking up a bottle of milk or whatever in a supermarket or elsewhere doesn't yet make a contract and that the goods haven't actually legally changed hands at that point. It's only when you're presenting your chosen goods at the register that you're legally making an offer to buy those goods, and unless there's a law specifically mandating cash acceptance for shops, the merchant (as represented by the cashier or a self-service checkout machine) is free to simply refuse your contract offer. And because in that case no contract was ever successfully made, there's no debt, either, and the concept of legal tender doesn't even enter into it…
