JANE MacQUITTY refuses to be duped by 'dodgy waiters and restaurants on the fiddle', and she offers her top tips for getting one up on the 'unctuous sommelier' with advice on how to detect a faulty wine and, perhaps more importantly, how to send it back: 'Be prepared for any number of excuses. Don't take it personally, stick to your guns and avoid losing your temper.' MacQuitty's top wines of the week include 2002 Boundary Road Shiraz, Margaret River (down 1.50 to 4.49 until 13 November; Co-op).
