I do see your point of view that the customer was also very receptive.
However I have a point to make, how do you know in advance whether the customer is receptive or not? So the best policy for a sales person is to 'presume' that the customer is receptive and go about business of selling, however one can expect to see unresponsive customers from time to time. Over a period of time you can 'smell' a good customer from a distance.
Secondly the so called 'unresponsive' customer also begins to become 'responsive'!
That's when the pleasure of being a sales' marketing person begins!
