Something to consider as well, even if secodary, is why are you getting this obstacle to arrise with any frequency. I'm not implying that your approach is wrong, but it is possible that there is something you are doing or saying that might be the root cause of this. Not everyone has to drive up in the newest van wearing the crispist uniform, and deliver the best presentation; however appearance, demeanor, and especially body language say a lot to a prospective customer before you even say a word. For example; I would never ask our new car dealer if they bought the new break pads for my wife's car, could they purchase them cheaper and then pass the savings on to me. Other car repair shops might even advertise or promote that feature. I'm not saying that our businesses are exactly like a car business, or that anyone here operates like a shade tree mechanic. I'm just saying that if I started getting difficult resistance from my customers that wasn't usual or unexpected, I would look inside our business for the answer first.
