Hi Dave,
Thank you for attending to my garage doors to-day. They are working beautifully now. When I telephoned you I never dreamed that you would return my call in such a short time and arrive at my house within hours that is what I call GOOD BUSINESS. I have never had such prompt service, knowledgeable, informative and a lesson on how to use 10W30 motor oil. I so appreciated his service and education all delivered in such a pleasant fashion. Thank you once again Dave.
