A DUI can cost $15k or more, so if there are some folks in your group who have been known to overindulge, a pocket breathalyzer might be a good gift for your white elephant party. They’re fun to play with but they can also prevent people from making some very serious mistakes. There are a range of mini breathalyzers available from $15 to $100 or more. Many are small enough to keep on a keychain.
