When I was young I remember that banks often had large drive-thrus with pneumatic tube systems at each car stall.
There would only be one teller but they could serve quite a few lanes.
If you wanted a cash withdrawal, you might put your ID and your withdrawal slip in the tube, and a few minutes later it would come back with cash in it.
It was pretty rad. But ATMs seem like a better bet overall.
Wouldn’t be surprised if there was an exceptionally well funded US startup that makes a debut before TikTok is blocked if they don’t sell. TikTok has to weigh the possibility that they can’t compete if they don’t exist.
