Note to young : Whenever you are in the airport, never ever be generous as to help anyone in carrying his item or accompany any lone traveler.
This includes : "Can you deliver these phones to my family? they will be in airport." -- trap, these are illegal and you have to pay.
"Can you accompany my sick father, people will pick him off airport." -- trap, no one will be at airport, and you have to send him to his home or hospital on your expense. And then also face charges.
"Can you drop me off at city center on your transport?" -- trap, he is carrying wine bottles and you will be arrested with your car. He can't safely exit without your help.
or even "Can you guard these packages for me, while I go to toilet?" -- he won't return in any meaningful time.
Help ONLY when you are contacted for help at home days before the flight and you know pretty well who you are dealing with.
Never help on the spot in an airport, for which you didn't agree on the previous day, or you didn't know him yesterday. Basically never make a deal in the airport, you will be the loser.
