Being a technician, I can tell you if you treat us with respect, we leave phone numbers behind. I drive a company van. I don't mind using their gas on a day off to go work. I've driven 2 1/2 hours before to go bury a cable for a guy who lives in the woods, and needed a pole mount. But when I came back, coffee, tea, food, and money were awaiting me. It pays to be respectful, we work hard. (Edit) And let me tell you, we don't get paid enough, but we understand customer frustration. Believe me, we are customers too.
