Man I showed up to a hostel in Barcelona with a full suitcase and the guy asked if I was eloping.

Look, I get the frustration but I disagree. Putting stuff back is the customer's job. The store pays people to stock and clean up. That's literally part of the job description. Nobody forced them to work retail. It's a job like any other. If you buy something and change your mind, just hand it to an employee. They get paid to deal with it. Walking it back yourself is nice but it's not your responsibility. Stores already build that labor into their payroll.

So we're basically memory mechanics now, but the emotional labor is still free.
