As you walk through the arrival hall a friendly person approaches you and may offer to carry your weighty bags or push your trolley for you. Although they appear helpful, they will demand cash payment for helping you. They will not return your possession until you hand overpayment. So be cautious from such scam artists and never let your baggage to touch and keep a close watch on all your belongings. Your collected luggage should keep in front of you at all times.
