Don’t worry, all such business inquires are politely declined.
The same guy pedals his bike by my apartment every other day. His handle bars are loaded with platic bags near bursting with knock off watches. Every single time I see him he doesn’t fail to ask: “Sir, buy watch?” Each time I tell him no thanks. He will respond with: “Very special gift, sir.” Normally I say no thanks again and move on. One day I’m going to say: “Oh! A very SPECIAL gift? Why didn’t you say so!”
I want ask him if he understands the definition of insanity. Then again, I suppose just by asking if I want to buy a watch he has already done more work in one moment than the entire OWS crowd combined. In that case, I’m not mad at him.
