You need some help Sir?

Yesterday I was roaming around just like that in Best Buy (a big electronic store). I was not interested in purchasing anything. Sudeep wanted to buy something. As I particularly don't like shopping so I started roaming around seeing what all is kept. Suddenly a customer support guy comes and says "You need some help Sir?". I said "No". And started walking. Again he comes to me and says "You need some help Sir?". I looked at him and his stare told me don't loiter around. I told him. "You know what, my friend is the person who might need help" and took him to Sudeep to get rid of him.
