You’re at a self-checkout register at the grocery store and among the items you’re buying is beer or wine. You scan the barcode on the beer or wine but can’t progress through the check-out process until an attendant verifies that you’re legally old enough to buy it. In your case, verifying your legality requires not careful scrutiny of your identification – doesn’t require you to produce any ID at all – but barely half a glance from the attendant standing 25 feet away from you. Before you realize that you’ve been stopped mid-checkout, she’s already pushed the override button. On your way out you pretend to not see the sign that says “We ID anyone under 40.”
