Huh...have encountered such people often...NEVER game them a single penny...I dont even listen to them...
At traffic lights people on bikes, walking along their bike, will come to me, knock on my window (I will NEVER open my window for them)...but they will start talking anyway and I will hear them saying 'bike mein petrol khatam ho gaya hai...thorey pese de dein...etc etc'...I will just drive on green light without answering them...
Some people will come to your car and start pointing towards your tire...to make you open your window and ask them whats wrong...and when you open your window, they will start begging you for money...
Sometimes a whole family will come to you with their kids, with luggage in their hand..and say they missed the bus...they dont have money...they have to go to etc etc place...they need money...
Well...I have never been fooled by any of these Pakistani bhais.
