In more detail:
I had a somewhat disreputable fellow walk up to me and ask if I liked music CDs. I thought this a rather unusual question but I said "sure." He then told me that he had a friend of his nearby that had a bundle of 21 CDs that I could buy. I told him, "That's okay. I'm fine with what I've got." He then walked off.
I do wonder what would've happened if I went with him. Would've it been a classic mugging? Were they real CDs that "fell off a truck" somewhere? Bad CD-Rs? Who knows.
The other question is, "Why a pet store?"
