that's a fraud... we also encounter the same... we didn't give money, instead we told them we will call a friend who has a cash on hand right now... and the guy start his car and left right away... maybe he thought we are calling the police... after 3 days, when we parked in souq waqif, we again encounter like that with another family but their words are exactly the same... i think this is a syndicate with scripted words to fool other people... be carefull...
