I've noticed it in the last two weeks at my favorite steakhouse in Boulder, Front Range Firehouse Grill. They light tables on the bar that popup a LN invoice QR code to pay your tab. You just select the tip you want to leave, and invoice changes to reflect that. They are onboarding folks at a rapid pace!
What lightning wallet do folks onboard with there now given high onchain fees and wallets like Blink, WoS, Alby not being available?

Most are using the embedded node in Zeus LN or the Blockstream Green experimental embedded lightning node. The owner has an uncle Jim setup and is running eCash and giving out nutjobs or something like that for the regulars.

I will have to try this out. Absolutely love Boulder, and randomly find myself in Colorado from time to time.
