Hi Stewart
I do a lot of canvassing, do,nt generally start till 4pm and work all the way through til 8pm, it,s the best time to catch the majority of people in.
Smart dress never hurts, in fact people generally buy the person first, the service is usually a bonus 4 them especially if u r conscientious courteous and do a good job 4 them.
Generally say this.... Hi there, just wondered if u have a window cleaner at the moment, Customer... Yes... obviously move on.
Customer....No... to this i just say would u like one?
