Once happend to me
i told to him:
i need the exact cash my agent asked you for,
i have to give percentage to her, if not i cant see you today,
he then immediately went to his hotel safe and took the rest of the money
and he turn to be quite tender and gentleman, i cant deny i got scared at the beginning, i was at his hotel
its a risk, but if you need to work, ...
its your decision.
Take care
