Here's an example (not mine): https://old.reddit.com/r/mildlyinfuriating/comments/1s0n9al/...

I also saw this in a gas station convenience store near me but I did not take a photo. I haven't seen it in a real grocery store yet.

There's a store in my neighborhood that only does app purchases and a little robot brings it out to your car. It's nice getting cilantro that hasn't been picked over by a hundred people, but I don't like shopping for groceries online, and AFAIK you can't actually enter the store.
