Drivers Licence/debit Card, interchangeable? Options

[lunk]

A friend of mine, walked into a government liquor store, here in Canada.
He bought some beer, and went to pay with his debit card.

Accidentally, he used his drivers license instead.
He swiped his D/L through the debit machine card reader,
the same one that's in every business, and the machine
asked him for his pin number.

So he entered it.

Didn't work.
It wasn't till then, that he noticed that he had used
the wrong plastic card.

All the gas stations here make it so you have to pay in advance,
or use credit or debit cards at the pump.

I heard something somewhere that your drivers license may work too.

...I wonder how they bill you, through your bank, or credit card,
or the department of motor vehicles...


...probably all three
...with interest
...compounding

imo, lunk
