Indians always do that. Very calculating and manipulative people. Most are dishonest. I'm always extremely cautious when visiting India as there are times that I do not have a choice but go there for professional reasons. For anything you give them, there is a calculated purpose and a calculated return expected.

In your case, this is another classic example of why one should be extremely cautious when dealing with strangers but even far more extremely cautious when dealing with strangers from certain countries such as India and those in the African continent.

True, scammers are everywhere on this planet but Indian and African scams are some of the most pernicious ones you will encounter.

Harsh as the above may sound but it represents the reality of the situation. Transacting with such people is a major PITA. They always try to get one message across: we Indians are to be trusted while you and everyone else are not. The symptoms are common: they always begin conversations with brother, dear, love, kitten, honey, sweety pie and similar nonsense and proceed with trying to dissect you financially. 150 Euros may not be much for Europeans but in India this amount converts to enough Rupees to buy them a whole month' worth of curry food.

Always use escrow.
