Back in the day, Ricky The Rat would drop a dime and rat you out to the cops.
The Syndicate never managed to finger Ricky, so they muscled the phone company into raising the price of a call from ten cents to a quarter.
“Exact change, please,” said the operator to Ricky.
That kept Ricky quiet for a while… until 911 made it to the city. That was toll free.
Ricky would still drop a dime out of habit, and get it back.
Then, cell phones took over. Phone booths vanished.
The Syndicate tracked Ricky with GPS, and whacked him.
