Either way, I suggest you get a good 7mm wetsuit. With such thin skin you're gonna have a rough go of it in this hobby.
The idiom "thin-skinned" applies to how people handle criticism, and has nothing to do with one's tolerance for a lack of quality. If you'll note, I haven't even responded to others' less-than-complimentary things said about me/my situation on this board. They don't know me and I don't know them, and that sort of anonymity lends itself to folks saying all kinds of things that they wouldn't say to someone in person. So perhaps you don't mean "thin-skinned", but mean "high-maintenance"? If so, I think I agree with you. I am high maintenance to the extent that when I pay a premium price for a premium product, I expect to have excellent quality and excellent customer service. Take this as an example:
I purchased an over/under sporting clays shotgun last week and received it yesterday . . . well, kind of. The seller (a very large gun shop in Minnesota) sent me the completely wrong gun. Bummed that I couldn't go play with my new toy though I was, I made a call first thing this morning to them. After a quick check of the documentation (I mean about 5 minutes total), I received a call back saying that the clerk with whom I had spoke wrote down the wrong sku number and said that they'll be shipping the correct gun out today with a prepaid return label for the other gun, and just asked that I bring the wrong gun back to the firearms dealer (can't ship firearms directly to an individual). In essence, they're drop shipping the gun. I made sure that they knew that I had the gun in my possession, and they were fine with that. I didn't bark at them because I'll have to pay another $35 transfer fee because a) they handled the matter so quickly in a way that was satisfactory to me, and b) because I saw how they handled the situation, I'm confident that they'll figure out a way to make it up to me on the next purchase.
Note that the seller didn't require me to "send any pictures" proving that they sent the wrong gun. They acted quickly and decisively. I'm confident that if there were no federal law requiring them to send guns to an FFL, they would have sent it to me directly and just asked me to send back the other gun. I call that "good" customer service, and Atomic could learn from that. It's not as good as if they would have either a) sent the correct order in the first place or b) sent me an upgraded gun, but it is still good. Also important is that they admitted their mistake and didn't even suggest that it was my fault because I could have prevented it by paying closer attention to the receipt they emailed me.
So, yes, I expect this kind of customer service and if that is high maintenance, then I am that. Otherwise, I couldn't care less about what people say about me as long as it's not a blatant lie. In other words, you can call me whatever names you want to call me - if it's subjective (an opinion), then by all means, say every negative thing you want to about me. As long as you don't say that I did something that I didn't, I'm going to let the rest of it slide even though I may disagree.
To sum it up: High Maintenance? Yes. Thin-skinned? No.
