I'd silently think to myself... OMG I've met a stalker from Home... I'd politely excuse myself to go to the bathroom. Then I'd head for the back entrance and get the heck out of there as fast as I could.
I am safe, I don't date in RL. If I met someone casually though, and they mentioned they were gamers, I would decide if I should let them know or not. I might pull what most people my age do when they see someone with a hand held in RL and say" Do it play " Pac Man"?
