None of this is directed at anyone in this thread but I think many of the vendors here will probably agree and relate:
Some people need to take a step back and look at this from the other side of the fence. I am often a consumer but run a consumer based business every day. It can get a little tiring when you spend 2 hours on the phone with someone (away from the truck on the lift) only for them to turn around buy the POS kit and POS converter you told them not to buy, to save a couple hundred bucks - thing is you could have gotten them that POS kit and POS converter for even cheaper if you didn't give a sh*t and were willing to sell your customers junk. Then a week later when their kit comes and the "shop" they bought it from can't help them, they call YOU and expect YOU to fix their transmission over the phone, for free - sadly you are nice enough to spend 2 more hours on the phone with them walking them through it while your dinner gets cold. Then 2 months later when their transmission is having problems you spend another hour on the phone helping them trouble shoot it, then they try to guilt you into giving them parts to fix it for free - like you should feel bad that they got "ripped off" by the "shop" that sold them a POS kit and converter - the same kit you told them not to buy the first time you spent 2 hours on the phone with them. Should we even get into the subject of all the guys that don't have actual shops or do actual work on their own truck (if they even have one) let alone anyone else's - but yet they are John Doe's Diesel Performance and undercut everyone else to make a buck or "hook someone up" - these are the same "shops" that we have to pick up the slack for when their customers can't get technical support for what they bought. And then customers wonder why we don't want to waste our time price matching John Doe's unadvertised price to make $15 profit on a deal that takes 2 hours back and forth on the phone with the customer and supplier to take care of - sorry but real shops usually have an overhead (aka bills to pay).
So sorry ahead of time to anyone that gets a hold of one of us at the end of a day full of that stuff when we have just had enough and want to eat our cold dinner - we may be short with you. Even if that's not the case some of us still believe that respect has to be mutually earned - so if you call acting like your money makes your sh*t not stink, don't expect us to kiss your feet - respect can't be bought, at least not from respectable people.
