She was smart about the refusal. Blood tests are accurate, the Breathalyzer is only as honest as the person giving the test. That said, it was a dumb thing to do. FYI it takes the liver about one hour to get rid of 1 oz. 100 proof spirits, 5 oz wine, or 12 oz beer( based on a 150# person). I have taught a server alcohol class since 1996, managed restaurants and clubs, and am also 20 year recovered alcoholic. The most evil of all drugs, alcohol, she should have gotten a fat sack instead. Good luck Alexandra.
