Alcohol Vending Machines?

You can get soda, potato chips and candy bars from a vending machine. Why not booze? 

Pennsylvania's Liquor Control Board is close to rolling out a pilot program to allow sales of hard liquor at wine vending kiosks inside grocery stores.

 WGAL-TV says the agency plans to test the sales in about five or 10 locations, possibly starting in the next few weeks.

 The station says some of the few dozen machines now operating are selling only a couple of bottles per day. A board official says what kind of hard-liquor products will be available through the machines hasn't been decided.

In order to buy the adult beverages buyers have to swipe their ID and breathe into a sensor to make sure they're old enough and sober enough to purchase alcohol.

Would you use a vending machine to purchase alcohol?  Is this a bad idea?
