Just reading through this thread, it's interesting how people interpret situations. Joe is my local RFD, and no, he doesn't suffer fools gladly, he speaks his mind, and will give an honest opinion, whether you like it or not, even if it costs him a sale. And boy does he love to wind people up for fun, especially the "know it all's".
Ask for his help/advice, and you'll be hard stretched to find better, start telling him his business, and you're more than likely get an ear full.
"Brand for brand", I've always found his pricing there, or there abouts, there may be the odd exception, but show me a shop where that isn't the case.
As for the "leaving the door open" incident, I think it's hilarious. By your own admission, you walked in from a snow storm, looking like a snowman, and then take offense when he cracks a joke/comments about shutting the door you left open
Personally, I'd have felt a bit of a plonker for not having closed the door, and not taken offence for being asked to do so. Some people clearly have thicker skins than others....................
