Scenario: It's another busy night at work. A young woman steps up to buy a pack of cigarettes and you ask to see her ID, but customers are lining up, so you glance at it quickly. The ID looks legitimate. While you didn't verify her age by looking at the date in the "UNDER 21 UNTIL" bar under the photo on the ID, at least you asked to see the ID. So you make the sale.

If the sale was illegal, could you personally be fined?
