Look them directly in the eyes when you say 'No' - this puts them off everytime.
I have tried the looking in the eye thing for touts and beggars, and it works sometimes and most times does not. I have now learned when someone persists in tugging at my clothes or puts unwanted goods in front of my face, I just put the palm of my hand right up in their face and say “NO” ... this has never failed me!
Connaught Place is the worst for being bothered
