Another Blistering Hot Take

Every self-checkout kiosk should recognize when the customer has begun paying on the point-of-sale (POS) machine and not require you to push a button that says "I'm going to use the other machine to pay now."

Walmart gets it right: it asks you how you're going to pay and then, when you start paying with a card, it goes, "Oh, he's paying with a card."

Every other grocery store on Earth, however, won't start taking information from the POS machine until you tell it to. Even though I'd be pretty confident estimating that at least 95% of shoppers use a card to pay.
