And there was pneumatic messaging ( buizenpost ) at retail shops ( I only remember C&A ).

Banks as well for money, and internal mail at many large companies.

Sadly the Prague pneumatic post system was damaged by the 2002 floods and hasn't been repaired since. Otherwise there's a chance that it still would have been operating on a city scale. That one could send money between banks.

Neat! London had a similar system.
