I have come across such cases also but in every case the people did not ask me for money but asked to buy them food. I did that. One must keep in mind the realities on the ground. People come here with a job, get thrown out in a few months by the companies, do not get salaries, and they carry a worry of how to repay the loan they took back home to buy the visa. This keeps them running around even on a empty stomach to look for some job opportunity somewhere. It is good that they were not forced into crime.
