I don't live in TN, but I think this is a good idea - they just didn't take it far enough. They set a standard for beer sales - EVERYONE gets carded. It takes away the failure point of the occasional 'idiot' counter worker's opinion that "This guy looks old enough, while this other guy looks too young". There needs to be a set standard for alcohol sales. Unfortunately, they stopped short of requiring ID for ALL alcoholic beverage sales. Face it - it takes almost 8 seconds to show ID. If that's too much hassle to buy alcohol, and pisses you off, maybe you should stick to diet coke...
