Ah, ok, I'm tracking you now. I think the confusion is that is not been my experience. Every food truck I've went to go order, pay, wait, receive food. I don't think your central premise holds, however. You may be reading too much between the lines or giving too much credence to a colloquial (and perhaps incorrect) interpretation. "when a debt has been incurred by one party to another, and the parties have agreed that cash is to be the medium of exchange, then legal tender must be accepted if it is proffered in satisfaction of that debt. However, otherwise the selling party may set the medium of exchange to be anything they choose: dollars, bananas, precious gems, feathers, whiskey, etc. They may also choose to accept cash payment only via alternative forms (e.g., credit/debit card, check, money order) rather than currency itself." https://www.snopes.com/fact-check/legal-tender-payment/ https://www.snopes.com/fact-check/legal-tender-payment/
