Drive Throughs

I'm a big fan of drive throughs at fast food places. The industry has changed their focus to make sure that the drive up customer gets their orders extremely fast.

Now, I see that the Heights Walmart is putting in a drive up window. You can order your specific groceries on their app, and when you drive to the store, somebody has done your shopping for you. Hmmm.

What's the next business that will install drive up windows?
