As I pointed out earlier, an hour after one drink you have a 0.00 reading. This lady was stalling.

Care to calculate the amount of time to go from being presumed legally drunk to no reading at all, 0.0000? About a day.

Wrong. Your body rids itself of about an ounce of alcohol per hour.. hence the rule of thumb for drinking and driving that almost EVERY bar tender can give you.
