• Don’t place stuff on conveyor at security, until way is clear to walk through
• Don’t be distracted away from case, valuables not all in one place/pocket
• Pickpockets bump into people, at bottle necks & info desks (travel with a photocopy of passport)
• Don’t connect to free Wifi, if unsure whether it’s official
• False greeters, who copy other signs & charge high rates or claim meter broken
• Rouge luggage helpers, who want money once they assist, even slightly
• Hidden call charges or accidental use, on your own & other mobile phone deals
• Leave your Bluetooth off to save power & stop access by others
