I was thinking of such system, but the problem is that you cannot wait several minutes or more in front of the cashier that someone will pay the bill, it must be automated where sats are locked by seller (the user trying to pay a qr code), bot scan the code, check that the sats are locked, pay thr QR fiat, seller confirmed it's paid, bot redeem the sats.

But for this you need an automated way to pay these QR code and it's often not provided but the supplier if not completed banned/blocked if detected.

But the idea is cool, I will give it a try.
