Sorry, I should have been cleared that I was referring to the part about the middle class waking up to the abuse of service workers. I'm pretty sure that many local stores treat their employees as bad if not worse than Amazon.
Delivery dates shift. Amazon's are doubly fluid. You might have to stay at home for a whole week have a reasonable chance of being there when the package deigns to be delivered.
I'm in the UK, I can have stuff delivered to my office, my home, a remote access anytime locker, a local store or a friend's house. I really don't have an excuse for someone not being there.
