I'm a dispatcher for a concrete company in the midwest, so I work with a bunch of rednecks basically. They chew tobacco, they all have a second job working on cars or excavating and they are all against having a black president. Naturally I never mention my hobby, I make it sound like I spend my friday nights playing poker with old highschool buddies.
My cover had never been endanger until recently. A friend of mine ran a comic shop until a few months ago and while it was open we played there. We played table top but there were also magic tournaments there on different days. I was the guy who organized all the table top events, and a few times I noticed my friend talking with one of the magic guys, and I got the impression he was the leader of the organizer of the magic players. He and I knew of each other but never really talked.
A few weeks ago I went out into the shop to ask about a broken down truck and to my horror that guy was talking with my shop foreman. He had a auto parts store shirt on. I instantly shot him a weird look, and once he noticed me he did the same. I talked to the shop foreman for a few moments, and during that time it was palpable that both of us were worried the other would say something stupid and out the other.
I walked away and we never acknowledge each other besides that look. It made me feel like my friends comic shop was some kind of speakeasy or something.
