As I stood next to mom, I could here and perhaps tell where the metal tubes were moving in the ceiling. In about a minute or two the canister would return with mom's change. How that tube knew exactly where to go and return to still boggles my mind. All those stores are now gone from downtown Lancaster as well as the pneumatic tube systems they once used, but the local hospital, newspaper and banks still employ the pneumatic systems. And, I'm sure they have an extra supply of canisters for customers like me that forget to put the tube back in the system and drive away with it. Seems they were never able to patent a unit that would stop the pilferage of their canisters by customers such as me. It was another extraordinary day in the life of an ordinary guy.
