Pretty sure that policy is already all over the U.S. to some degree, although it’s an unwritten policy AFAIK. Around 13 to 15 years ago I wanted to go buy a used car from some small used car lot place. I saw a car I wanted but it was like $8,000, figured I could haggle them down to at least 7k if I had cash…..So I went to my bank that same day, talked to the teller and told her I needed 8k from my account which was like 80% of my savings at the time, and the bitch said “we can’t do that”, I was like “why can’t you? it’s my money, not yours”, she asked what I needed the money for which pissed me off because it was none of her business to begin with, but I answered in an irritated voice “it’s for a used car”, she said the best she could do is give me a cashiers check and I kind of raged “HOW AM I SUPPOSED TO HAGGLE WITH A CASHIERS CHECK?”……luckily, my cousin’s ex GF was the manager at that bank, she heard me getting loud with the teller and stepped in. I explained the situation to her and she said “I’m not even sure if we have enough money to cover that amount with the demand we typically have on a Friday. That was back when not everybody had debit cards and a lot of places didn’t accept debit cards as payment….anyway, my cousin’s ex went into the back of the bank, came out with a bunch of wrapped Benjamins and gave me what I asked for, but holy fuck, between the argument and having her get my money, it took a good 45 minutes, and I’m pretty sure they weren’t going to give me my money if I didn’t happen to know the manager. I saw a vid on social media a few years ago with a dude who went through the exact same situation, but the bank denied him, and cops showed up because he was making a scene. I bet that shit happens regularly.
