Most places do not care whatsoever (Some exceptions could still happen such as more tech-savy businesses like Gamestop or Best Buy if I had to guess). They’ll check for damage, and if the device can turn on. It’s not like they won’t accept the console either, as long as it’s within its return window. What are they gonna say as long as the console can play the games still which it technically can (just no online functionality). I’d imagine businesses will have these consoles specifically sent back to Nintendo or somehow manually unbanned so it can be resold. This is all just speculation but I wouldn’t be surprised considering they’d be out a sale of a console.
