} coffee. But 98% of the cash that customers offer is counterfeit. How
} would this affect the way that cashiers work? Would they just accept
} all the cash and figure they'll call the cops when they find bogus
} stuff?
I suspect they'd make everyone pay in advance so they have time to
confirm the cash is real, and then only provide service to those who
have an account in good standing. Then it may turn into a problem
with identity theft, but that doesn't hit their bottom line.
Then 98% pay with fake versions of whatever it is that they give you
to say that you have an account. Same problem. This isn't a perfect
analogy, since at a donut store you rarely have 1000 people
simultaneously at 1000 counters trying to buy a donut with the same
card that has only 50 cents on it.
} ... if your wonderful system rejects their fake stamps with 99%
} accuracy, they try 100 times as often ...
.... Let through unchecked anyone with a history of payment and
throttle everyone else (to the point of quarantine without final
delivery, if necessary) until you know their history.
That's what Turntide does, except for "history of wanted mail."
Why would "history of paying" be better?
