Since we sell used cars, I feel for both the salesmen and the customer. Yes, you should take every person seriously. There have been many times that I have under estimated people that walk in and have regretted it.
However, I see more and more these days that buyers are getting slimmer and more and more tire-kickers come in. You have to understand that sometimes you will catch someone with a short fuse. We work from 9-6 Monday-Friday & Saturday 10-4. 90% of the people that come in don't buy cars. It is very frustrating these days.
We got rid of all the salesmen after 9-11 so we sell the cars ourself. This way, if we blow a sale we only have ourselves to blame. We are more of a laid back dealership. I wait untill the people come in or I wait untill they go and look at the car. There is no reason to go raging at the customers before they get out of their cars.
