I dont know what choices those girls made or were forced to make and i'm on the fence with this, at the moment.
Many years ago, at age 19, my friend and i, both female, did some travelling together in Thailand.
In our final week before returning home, a stranger 'attached' himself to us, started paying for everything, for our meals and our hotel, despite us refusing and insisting we pay our own way, our bills were constantly settled by this stalker, against our wishes. We had a really bad feeling about it straight away.
Sure enough as our flight home drew nearer, this man decided we 'owed' him. He started putting alot of pressure on us to take a hold all bag back home with us. Gifts for his family, he said.
He got verbally aggressive when we were reluctant, although he didnt actually threaten us as far as i recall.
We were, of course, massively sceptical, but we certainly werent brave enough for open derision!
We could not get rid of him and he would not take no for an answer.
In the end, out of desperation, we told him a load of lies and ended up literally hiding at the airport for several days to avoid him and his bag.
It would have been so very very easy to agree to do it and he wasnt even offering to pay us!
If we, or our families, had been physically threatened, the outcome may have been very different.
Without knowing the full story, I do sympathise with these girls. They may have made a very stupid decision but i very much doubt it was pure greed motivating them.
