I work in a factory. The change machine gives back dollar coins, so I try to avoid using it and ending up with 10 pounds of change in the bottom of my purse.
However, the coins work OK in the vending machine.
Of course, the vending machines now take credit cards also.
The gal who drives the break truck (”roach coach” or “maggot wagon”) prefers traditional bills and coins.
I pack my lunch most of the time but sometimes I need more coffee or more Mountain Dew to keep rolling.
The vendors prefer standard coins because they have their machines everywhere. Plus, the coin activated machinery works better than that activated by bills ~ although pre-paid credit cards are catching up quickly (and are standard for small purchase situations in Europe).
Eventually we'll have replicating machines that read our minds and give us exactly what we think we want to eat ~ and all without dropping any coins in a slot or trying to push worn out bills where they can't go.
The machines in those days will simply tap our accounts on their own!
I want to own the machines fur shur.
At the moment, those coins are piling up because business, and employment, is down. Could be the pre-paid credit cards are making their way into the markets as well.
