I'd seen Affleck in the store a few times (with Gwyneth Paltrow) and he typically looked all jock-y then. The stuff he purchased, he'd literally throw on the counter and say, in a jock voice, "I want to buy this," while Gwyneth stood behind him, as if he were a shield, looking embarrassed. The bearded Affleck story was a couple of years later.
I'm not sure which southside store you're talking about — whether the one owned by the same guy who owned HRV or the other one. I went to the other one a couple of times, and you'd have either loved it or hated it. Probably a better comic shop than either of ours, but the owner blared AM talk radio all day.
I also sold some comics to Keanu Reeves once, which was very awkward. He was in a really bad wig disguise and I pretended not to recognize him. He had apparently just discovered Alan Moore and was asking questions about Moore's work; he wasn't trying to be low-key at all. He acted like he was just a regular dude shopping for comics, even though the guy I was working with kept finding opportunities to go, "Whoa!"
"The trouble with being a ghost writer or artist is that you must remain anonymous without credit.
If one wants the credit, one has to cease being a ghost and become a leader or innovator." — Bob Kane
