You’re wrong. Once a price in U.S. dollars has been determined, an agreement (contract) has been reached by the seller to exchange that good or service for a set amount of U.S. dollars. Once the contract is set, then the buyer can give the U.S. dollars agreed upon in any legal form.
The treasury notes are legal tender for all debts, public or private.
That means if there was a contract that the buyer would accept 5 U.S. dollars in exchange for the salad, then a $5 valued U.S. Treasury Note is a perfectly legal way for the buyer to fulfill his portion of the contract. It would be a breach of contract for the seller to renege based on the form of payment offered when the form of payment is legal tender for private debt.
Then I guess the contract to buy is broken. See ya.
You are wrong. To comply with the law, a store would have to keep thousands of dollars onhand every day to cash $100 bills when people use them to buy packs of gum because, according to you, they must accept the $100 bill to make change. It would be a failure to follow the law if they could not make change. The fact that they can refuse $100 bills also allows them to refuse $5 or change.
It’s not in their best interest to do that because it is foregoing income, but they can do that.
