I think it's a trait with these types that makes them what they are to begin with. They don't just turn it on and off for the bad guys, they're like this all the time with everyone.

Never meet your heroes is just great advice, same as it ever was.

I've met hundreds of celebs, and 99.9% of them are unbelievably nice and kind. The only two that have ever been gruff were Bill Shatner and Dean Stockwell, and honestly, they could have just been sick/tired/having a bad day.

I would say "meet your heroes"; most of them are probably going to be better than your expectations.
