Just had a chat with a colleague about things that have disappeared / almost disappeared over very recent years -
Remember carbon paper ?
I remember writing a letter out long hand - sending it to the typing pool - receiving letter back - correcting typing errors - sending back to typing pool .
Oh how technology have come on a pace in a very short while .
Trivia fans - did you know that paper correction fluid, which became trademarked as Typex, was invented by the mother of Mike Nesmith from The Monkees.
When she died, Mrs N left half her $30 million dollar fortune to a charity, and the other half went to Mike.
Mike went on to carve out a second eight-figure bank balance as a musician and song-writer, and then a third when he was in on the ground floor of pop videos on TV, which evolved into MTV.
Most large department stores had the 'Lamson' system, a network of tubes through which canisters were propelled by vacuum to the cashier. I can still remember the 'thud' it made when returned with the change.
If these systems are still in use then it is internal transfer of cash. I was thinking of the time when the salesperson wrote out a receipt, put it in the canister with your money, sent it off and you had to wait for the change coming back.
