I would never feel comfortable having someone else doing my shopping for me - unless i was severely incapacitated for some reason of course.
Same with cooking, cleaning, washing my clothes etc. I could pay someone to do that but I get a lot of joy out of basic chores I guess.
I'm not sure what the thought process was there. Walmart went from me doing most of the work to them doing almost everything. The day pickup stops being free, I'll likely just throw in the towel and start paying more to get groceries from another chain.
1) Pickup is asynchronous, so no long lines will form. If it's busy you get the notification ~15 minutes later than you normally would
2) There's no possibility of shop lifting (not saying that _you_ steal, but inevitably some people do)
3) Maybe the parking lot or the store is actually full (fire code) and the actually amount of commerce is being bottlenecked by people in the store. You can literally just sell more stuff if you have everyone do a 2 minutes pickup.
4) Pickup selection requires you to go into the app, perhaps where they have opportunities to upsell you in clever algorithmic ways.
Chalk it up as a win-win. Not everything has to be either they lose or I lose
