Agree to disagree, I suppose. I don't recall anything about the PC making a very high Int check to value the armor, although perhaps I missed that (in a subsequent post??). If he did that at the time, I'd certainly be more forgiving...although I'd still be inclined to say "You begin to remove the Gauntlets and the embedded ring when the blacksmith says 'Whoa, whoa, you agreed to sell me this whole set, where do you think you're going with those? A deal is a deal and those are mine now, son.'"
Were it my character, in any event, I'd have my character take the blame and play that for comedic effect--that the character made this awful deal because he was inattentive, and the blacksmith was cutting me no slack.
It seems like that is how the bulk of the players are taking it, and rolling with the punch they aren't calling for a retcon, let alone an "apology." This is a game where we collaboratively make up a story to amuse ourselves. For all the work a DM puts in, how many "thanks you's" does he or she get? If an apology and contrition is warranted after a single misstep, then I would assume that heartfelt gratitude should be expressly offered to the DM by his or her players after every single session, if not every encounter.
In my opinion, a player would really have to be a special, and especially sensitive and entitled, snowflake to demand an "apology" from the DM who otherwise does most of the work involved in letting that player have a word to play in. If a player asked my DM for one...wow. If I were DMing and a player demanded one of me...I might paraphrase A Few Good Men:
"Son, we play in a world that is entirely fictional, and events in that world have to be invented and run by DMs. Who else's gonna do it? You? Who can barely be bothered to listen to the list of loot that I had to generate? I have a greater responsibility than you can possibly fathom. You weep for the lost Gauntlets and you curse the loss of a ring. You have that luxury. You have the luxury of (apparently) not knowing what I know, that the mistake your character made in selling those items, while tragic, probably advanced your character's story arc. And my existence, while grotesque and incomprehensible to you, allows you to advance that story arc! You don't want the truth, because deep down in places you don't talk about at parties, you want me running this world. You need me running this world. DMs use words like "encounters", "threats" "conflicts". We use these words as the backbone of many hours outside of the session spent creating something for the group's enjoyment. You use them as a complaint. I have neither the time nor the inclination to explain myself to a man who rises and sleeps under the blanket of the very entertainment that I provide, and then questions the manner in which I provide it! I would rather you just said "thank you", and went on your way. Otherwise, I suggest you pick up a DMG and some graph paper, and run your own game. Either way, I don't give a damn what you think you are entitled to!"
