I've told this story to many people over the years, and I think at least once in a Shatner thread here, but I went to see Shatner at a car show of all places, before Trek V came out. I don't know why he decided to show up at a car show but this was during a time when he did few if any conventions. He was too dignified for that, you see. But he decides to do a car show, with the intention to sign autographs. Well, maybe because he hadn't been doing cons, the place was mobbed, and he freaked out over the numbers, so rather than agree to sign, he gave out headshots and briefly shook people's hands and said hello. Now, for a teenager like me who idolized the guy and watched him on TJ Hooker, I was hoping for that little sliver of eye contact and recognition. I didn't want to hold up the line at all, just to have some genuine exchange of pleasantries. So I rehearsed this line in my head. I was going to say "Looking forward to seeing you in Star Trek V." That was it. That's all I wanted to say, and I was expecting him to just smile and say thank you. Well, after an interminable wait, I finally got up to shake his hand, and right as I opened my mouth to start to speak, he cut just cut me off by asking me my name, so I followed along, and he said nice to meet you, and that was it. I remember how clammy and soft his hand felt to this day.
Anyway, I'm sure there will be people here who will skewer me for how I handled the situation, that I went in with the wrong expectations, that my reaction was all my own fault, yada yada yada. All I can say is, at that point in time, it was pretty soul-crushing. Basically what he was doing was mechanically going through the motions like a robot. Never once did he really engage anybody the way a real person did. He looked straight through me.
So I didn't get an autograph and I didn't get any sort of genuine momentary connection that fans want in a situation like that. And this was way before his reputation for being a dick became public knowledge, so when that eventually happened, it made sense to me. This is why, by and large, I belong to team Takei.
My experiences at cons getting things signed by others did satisfy my desire to have that genuine "moment" with them, which included James Doohan, George Takei, and Nichelle Nichols. George wound up mishearing my name and writing my name wrong, but that was just due to the crowd.
And out of all of them I think Majel Barrett was the most down to earth because rather than just doing a talk and doing the signing after, she hung out on the floor. I don't remember if she actually had anything to sell (ala Lincoln Enterprises) but it was right before TNG came out and she was trying to drum up interest. But she definitely seemed like someone who liked being accessible to fans and wasn't just there for the money.
