That is really out of order on the lady.
I was a door to door salesman for 2 years,and sold gas and electric for 9 months,never signed anyone up if it wasnt cheaper,never nicked anything (although there were many opportunities),loved the job,met loads of nice people and made a very good living,was the best job ive had.
people like him give salesman a bad name and it really is only a small minority that are doing it.
