all year long i have been stopped in parking lots, driveways and gas stations by people who ask for a business card because they need our kind of service. i usually ask if they have any questions about our service and answer all questions in what i feel is a professional manner. i have given out probably 50 cards in this way and to date i have never gotten a single call from any of these people. what can i do to remedy this situation? is this the norm or am i leaving something out of the equation?
