The timing of this thread seems very, um, timely. Recently, I have run into this sortof behavior on multiple occasions, at my home course, Elver Park. Last weekend we teed off on the last hole, a huge downhill drive, and while walking to get my cousin's disc, noticed some guy from the group ahead just standing on the fairway. His group was already done throwing, so this struck me as strange, so i made a beeline for this guy. From the way he was talking before he tee'd off, he seemed like kindof a d-bag.
I asked him if he'd seen my cousin's white disc, and he looks aroudn for a second, then shuffles through the pile of 4 discs in his hand, and asks what kind. I tell him, and he drops it on the ground and walks away.
Also that round, we played with these three HS kids who overall were pretty cool. However, three times, I'd walk up to throw my second shot to find one of them walking out of the brush with my disc in his hand, thinking they'd found a new disc. This got old really fast, but I was polite about it (I was the one who kept shanking it into the brush).
Here's the problem with that situation, even if the disc they had found wasnt mine, I've got phone #s on all those discs, and not once did they flip over the disc and look for a # like they might call it.
That bothered me almost as much as having to take a drop from the approximate location of my drive, since htey would just toss the disc back down next to them and say, oh I found it about there.
Very trying. I've played with two or three disc wonders that were great players and some that outshot me. Most of them are cool. But I think the point is this, how many d-bags have you met on the course that carry innova bags with a dozen discs in them? Its not the experienced adopt-a-hole locals cracking bottles on the teepads.
