Yep - similarly: you live in a neighborhood with a local coffee store. Sure
you could use a stolen credit card or a fake $5 bill, but it's not worth

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.
