Drive thru store where you can get just basic items.
Like you pull up to the window and get windex, lucky charms, and a gallon of milk. You don't even have to get out of the car (or get your kid out of their car seat). There could be a 5 item limit or something. I know they already have online ordering for some grocery stores now, but this would just be a quick "I need these items and have no time or patience" kind of thing.
You go. What should there be?
