No most are what Dan calls "Trick or Treaters" they just want what ever you're giving away, the others do not want to make eye contact because they don't want to be sold anything.
So something like this they must get it in a second or two or it has little value.
What we do to break the ice is offer their kids a blow pop, then all of the sudden their facial expression changes and they say thanks and take a look at who you are and will ask a few questions. Its the most we can hope for, they may take a Air Duct clean brochure, ask a few questions about mold but it is an opportunity to do a dog and pony show of our services. It works quite well actually, a few duct jobs, some carpet cleaning, a few moisture inspections. A few years ago when I was about done with doing them we got a $60,000.00 account from a wdr client that didn't know we did commercial carpet cleaning. So we just never know how much actual value you get from them.
