"Chuckers", not golfers. Those of us who are the latter, know the difference and do the right thing.
But yes, it's a shame. I've lost 8 or 9 name and numbered discs in the last 3 years and I've only had 1 single disc returned (and it wasn't even one I really cared about). 4 of those were also at JB.
I really hope your Dylan disc makes it back to you. I know how much you like it.
