Was this guy a little anal?
We have a local guy with an amazing amount of all muscle car era makes and models parts yard. It is ridiculous in size and stash. He also has enough of thief’s killing his pay check. Now, you call for an appointment and you are met at the front door but never get in the office area. You pay outside and get your part.
He also doesn’t sell junk. When you get your part, it’s good to go. No half *** junk.
It is a real shame people screw these people and make it crappy for us all who would like nothing more than to just roam around and take time to get the part ourselves and maybe even learn something as you pass by it or take it out yourself.
The guy you ran into probably was “Bitten” more than just a few times and that’s why he came on stronger than needed. But the message was sent and received clearly as fine crystal.
As others have said, just go back and play it cool. You already apologized. Just be polite and smile say thanks, etc... be positive and cheerful. Tell him you’ll be back. Make him feel at ease. ThTs the best you can do. If he remains a grumpy bastard, there’s probably not much you can do. In the long run, he will see your not a bad person. Over enthusiastic maybe! LOL! But work towards that working relationship. It’ll payoff.
