Things We Want Back: Pneumatic Tubes

Wiki:

Pneumatic tubes (or capsule pipelines; Lamson tubes) are systems in which cylindrical containers are propelled through a network of tubes by compressed air or by vacuum. They are used for transporting solid objects, as opposed to more generic pipelines, which transport gases or fluids.

Pneumatic tube networks gained great prominence in the late 19th and early 20th century for businesses or administrations that needed to transport small but urgent packages (such as mail or money) over relatively short distances (within a building, or, at most, within a city). Some of these systems grew to great complexity, but they were eventually superseded by more modern methods of communication and courier transport, and are now much rarer than before.

A small number of pneumatic transportation systems were also built for larger cargo, to compete with more standard train and subway systems. However, these never gained as much popularity as practical systems.

I think costco stores have pneumatic tubes going to each checkout lane. You can kind of seem them here:
