Most people also don't have their wallet in their hands when they are walking around. This usability and natural action argument is sort of moot and non impactful to this a discussion. If I really wanted to keep arguing, I would say that people waiting in line to pay are probably browsing their phone while waiting, so the transition to paying is not cumbersome. It's still a terrible argument for Walmart Pay. But, not as bad as saying that folks won't use Walmart Pay because the buggy is occupying their hands. The probability of finding most things that are cheaper elsewhere than Walmart is extremely small. Their margins and their entire business model depends on that. So your anecdotes of people finding something cheaper is not material. And finally the good 'ole "solution looking for the problem." It seems it is more and more the default "I-cant-extrapolate-but-this-sounds-clever."
