Well it is done now and I have learned from my mistake.
Did you though? Look, I'm not trying to pile on here as others have explained the trading/flipping/depriving someone else thing far better than I ever could. But I don't feel like you truly understand why what you did was in such bad taste. Put aside all the value/flipping/deprivation comments for a second as those have been addressed. Instead, please realize that you did this in the artisans
home thread. This is where he does his does his sales, communicates with his patrons, and just about everything else.
Imagine we're in some random city and I see a craftsman, le't say a leather-worker, selling stuff out of his small road-side shop. He's got a large crowd around him and everyone seems to want one of his fancy horse saddles, and for good reason! So let's say I push my way through the crowd and clamor for a saddle just like everyone else...except it turns out he's only making a few, enough for about 5 of the 100 people gathered around. So the craftsman finishes up, picks five lucky winners out of the crowd and hands each of them a saddle...and I happen to be one of the lucky winners.
Now, imagine if my very next action was to turn around to the crowd, hold my saddle high up in the air and ask "Hey folks, what do you think I can get for this beautiful saddle that all of you were just trying to get?". What do you think the crowd is going to feel? What about the craftsman, whose store-front you're literally still standing in? Then imagine if, when questioned about said statement, I responded by saying "I'm not even really interested in this saddle anyway, I prefer a different style". Brutal...
Like I said, I'm not trying to pile on here and it seems you understand at least part of what was wrong about your post. However, I hope my (poor) example better illustrates why the response was magnified even further. Hopefully you can move on from this and take the lessons learned. Best of luck.
