I signed up a home inspector on Wednesday that was in his 70s. He has had his engineering and home inspection firm for over 30 years. I sent him a Thank You card on Friday. I received a long email yesterday from him talking about how he admires the way I do business. Then, he said he is now going to start using Thank You cards. It didn't hurt that I already had him on page one in less than a week(thanks Matt!).
Moral of the story-I guess you can teach an old dog new tricks!
