No matter what the "legal tender" is, if your store has been robbed multiple time and you fear for your life and the safety of your staff, you will post a big "NO CASH" sign on the door.
Maybe in California. It doesn't work that way in Texas. I'll give you a for instance. The time is 2008. I have accrued enough savings to pay off the mortgage. Go to the local JP Morgan Chase branch and indicate my intentions. Unfortunately, that large amount of cash is frowned upon when used to pay off a house note. So, after obtaining a cashier's check, free of charge from said Chase branch, I was heading on back to the house with deed in hand. Ok, so not everyone takes cash, but there has to be a workaround to accomplish the same result, in order to comply with the law. Otherwise, someone like me can cause you a hell of a headache.
The difference is most people won't go toe-to-toe with these corporations that have established an "our way or the highway" mentality. I sure will. I'm certainly not one of these people you see on YouTube, or wherever, that go stand in front of a police station with a camera saying "but I have a constitutional right, you can't stop me from filming!", however, if that's what they feel the need to do to get a little satisfaction from putting these overreaching publicly paid officials in check, I won't stand in the way. I will not just let anyone walk all over me, while I sit silent on the matter. That's the thing. We've allowed ourselves to become complacent in our lives and just let those with a little title do as they wish.
I don't think any court or any judge would do anything but throw out such a case.
Our Attorney General's office forced our local tax office to allow me entry to pay the property taxes on all of our land in 2020. Sans mask. No if, ands, or buts about it. They either let me in, or faced me never having to pay a property to ax to this county again. Not my words, those came directly out of Ken Paxton's office.
When it comes to certain rights, when you know them, and your family has spent a couple of generations of "conflict" fighting for them, there's not much they can do, other than to tuck their tail and walk away. That's just the reality of it. You have to be willing to fight, scratch, and claw to hold onto what little rights we have been guaranteed as a privilege to live in this nation. If we're expected to just roll over and play dead, letting these people have their power trip go unchecked, well hell, David. The both of us might as well sell out what we own collectively, and go live under Putin's thumb.
Airlines stopped taking cash decades ago, as the amount of money each ticket costs, the need to make change for large bills and other complications made doing so impossible.
I stopped taking flights after they decided to start stripping people down to their skivvies, so that's a wash. If I can't drive there, it ain't worth going.
I saw a TV drama where a guy bought a high-end car with cash late in the afternoon. The dealer put the money in the safe. The purchaser sent his crew late at night and blew open the safe and took the money.
I'd wager, even in the fantasyland of Hollywood television series, that the drama wasn't set anywhere in the South. That safe would've had cameras honed in on it from every angle, and further insurance of its safekeeping by the legendary firm of Smith & Wesson down here.
