Since cjk stole my thunder on the post he just made, I'll have to settle on something else equally interesting. And this situation is ultimately all about me, which is a good thing.
I recently bought a new laptop from Lenovo which I'm expecting to arrive by X-mas. After I bought it, the pending charge showed up on my bank account letting me know that while there was $X dollars there, about $600 of it was supposed to go away very soon. I checked the account this morning, and the $600 had magically reappeared in my "available balance."
So...what is the moral action in this case? Do I contact both Lenovo and my credit union to let them know something's up? Or do I just say, "Hey. They screwed up. And I get a free laptop out of it"? And if the first choice is the moral one, does that make the second choice immoral?
I have an idea of what I'm going to to, but I'm going to wait a week to see if the situation resolves itself. And I'll obviously pretend the money isn't there. But...what would you do?
