He was probably thinking "just a glove" or not my brand...Mmm, yeah, "lost" one of those once when I accidentally left it in the cart. Also "lost" a pair of Oakley sunglasses once the same way. It's a crappy feeling, and I'd never want to intentionally be a part of making somebody else feel the same way.
That glove I found and turned in the other day? Another guy drove past it right before me, slowed to look and see what it was, then drove right past and left it lying there. Why not make the small extra effort to pick it up and turn it in at the end of your round?
