It sucks when people don't act like we expect, or hope for. I hear that. I'm sorry you had to have that experience, because it feels awful. Been there, it's rough. And I totally get what you mean about wanting to support local game (or other kinds) of stores and be part of the community. That's a great thing and I hope even if you decide not to return to THIS store you'll keep doing supporting other local small businesses, because it's great and so meaningful. I wish they all acted in such a way that it made it easier on us to continue to give that support!
From all your other posts on this forum, I have glimpsed how deep your thinking and understanding is, and I would normally just leave it at the message above but I feel like in this place and with you specifically I can go on to something else... And please forgive me if this is out of line or doesn't feel kind. I don't mean that way.
What you do have, if there's a silver lining, is an amazing opportunity from this mess. And you probably already know this, but I think having brothers in faith remind us can be helpful. First, this allows for so much empathy the next time you're on the other side of the counter. Whether that's figurative or literal (I don't know your job) it means you have this very real and true experience to pull from so you can go out of your way to help someone else who is feeling what you did when you brought in the defective model. Is that empathy worth the frustration? I don't know, but if we use the empathy for good works, I have to believe it is.
Second there's also the amazing chance to practice the forgiveness that we're called to. I can't speak for you, but I know for me PERSONALLY when I am in those kinds of situations I can almost feel my heart get a little harder. I'm mad, dang it. And that anger is justified, too, which is the most dangerous kind of anger! Yet still we are called to be different. Just yesterday I was reading Eph 4:26-27. “In your anger do not sin” : Do not let the sun go down while you are still angry, and do not give the devil a foothold.
This is hard, and some days I kind of hate that it's how I'm supposed to act, but I see the wisdom in it and (forgive the assumption) I think you do too. Not that I'm claiming you're still mad, but if you are, just a hopefully-gentle reminder to breathe in the spirit and breathe out the blackness that wants desperately to control you like a puppet. You probably already know that forgiving the guy (who, let's be honest, may have been having a bad day or something in his life is such that he doesn't even see the hurt he's causing with his attitude) will set you
free more than anyone else.
Anyway, again, I hope I am not overstepping my bounds here. If so, I ask forgiveness and that you ignore me, because I DO NOT want to add to your misery here. It's already a crappy situation, and if I made it crappier with my comment, I'm truly sorry. Will be praying for peace for you, whatever you decide about future purchases at the shop!
