My plan eventually is to go and use one of those big coin operated breath testers they have in pubs - from what I've read those things are worth thousands of dollars and are based on the same technology as the police RBT units. My question is though, does anyone know of any places in Melbourne that has one, that isn't a complete yobbo hangout (cos unfortunatly that's where these things tend to be - they often go hand in hand with binge drinking venues).
