Punk, Lesnar, and Orton are guaranteed to be bad experiences from what I've read.
Lesnar doesn't belong on that list, he doesn't like being approached when with his family understandably but he's a cool cat with a dry sense of humor if you catch him outside of that
Jim Dodson
Used to let me and my buddies know where the wrestlers were going after shows here because he could tell we were fans but not psychos. I'd talk the poor guys ear off at house shows and he'd let me stay by the rail so I always got good pictures at WWE events. (I might start uploading them here)
Met the Nation of Domination after a house show Ron Simmons, Rock, Mark Henry, DLo.
shyt I've met a lot of wrestlers over the years
Have a pic with Stone Cold
Met Eddie the night he passed

he seemed in good spirits too.
Met Brian Pillman the night he passed after the house show
Met Taker after Summerslam 99. Ministry era but he was shockingly cool as hell
Met and talked to all 3 members of new day a few months ago at my gym cool ass dudes
Just need to meet Sting in person and I'm set and that'll be checked off my list later this year
never really had a bad interaction with any of them. It's all in the approach, if there's a lifetime fitness/24 hour fitness in walking distance (3-4 blocks) of the arena they're performing at go there around 7am the morning of especially if you wanna meet divas
