you could use a stolen credit card or a fake $5 bill, but it's not worth
the risk of being caught for a $3 coffee. And on the other side, the store
can deal with 1% of transactions getting reversed or having a fake bill so
they don't change their procedures.
Perfection is not necessary in all situations.
