Once you've gone through the entire list, you'll know within a two minutes if everything was delivered. If something's missing, I'll go through all the bags to triple check before calling customer service.
If you have extra items, simply keep them. I've contacted Amazon when I was delivered a few extra items I didn't order and their response was "I'm truly sorry that you have received an extra bag of goodies. You are welcome to keep, dispose of or donate the items in that extra bag." Their loss is your gain. Not a bad deal.
If you're missing anything – or, if you've received the wrong order – then contact Amazon. They will probably give you a refund and/or a credit and then, if time allows, send out the replacement items.
In my experience, all of the drivers for Prime Now have been Amazon Flex Drivers which is like Uber/Lyft, but instead of moving people, the driver is moving goods. However, the Flex Drivers do not pick and pack the items in the warehouse; that's done by well-trained Amazon employees and highly obedient robots.
To speed up my delivery, I will use the app or website to track the Flex Driver on the way to my place and meet them between my front door and the street. Your deliverer will appreciate that, especially if you live in a gated complex.
Like Uber/Lyft, no money is exchanged on the spot. It's all done ahead of time, through the app; even the tip.
Yes, Amazon's taking over the planet (and beyond). It's the second most valuable company in the world, if my calculations correct:
High Tech Market Capitalization
- Apple: $939B
- Amazon: $872B
- Google: $824B
- Microsoft: $801B

- Netflix: $180B
PS – No, you don't have to queue up your food to inventory it. I don't. I only did it for these photos.
