That was a private PM, offering you money for your product. He didn't insult you by calling you names, he didn't try to order you to sell him the product for a price that to him was unreasonable.
You then mock them for trying to buy your product. I can understand you might be frustrated by the offer, but responding like this is uncalled for, and I frankly am surprised someone like you is a business owner.
Poor taste.
Here is where you have the " I'm going to jump in and defend this guy " attitude all wrong.
1. I am not a business owner I buy and sell equipment out of my own pocket
2. There are low balls and thence are People that want something for nothing
3. Ask anyone that has purchased equipment from me I am more then fair if not cheaper I stand behind my work and product.
And lastly I'm sorry if you feel I'm being a ass hole but to many people think that this is ok to lowball the shit out of people. I'm just saying what some don't say
So you're not the business owner, AND you do unprofessional things in the stores name? (READ: your name does imply that anything you post is official business of Tempe Paintball)
Either you must really be good in with the owner, or you don't care about remaining employed.
Edit: It's also starting to really bother me, your spelling is atrocious. Wednesday is spelled Wednesday, not wensday (see every thread you've ever posted), and "WARRENTY " is spelled warranty.
The little red squiggly lines means something is spelled incorrectly.
