[Cue cool spy music]
Seeing how he was there on more then one night leads us to believe it is no longer a case of "so who comes to this bar?" or "I only stopped in for a beer".
So, you have 5 choices.
1) Stop going there, & hope to not see him at other like bars.
Phewwy! It's your bar, you like it, bad idea so lets move on.
2) Ignore him & hope he goes away before seeing you.
Again, bad idea, Your just not going to have fun there always wondering if he is just around the corner.
3) Have a friend [do some recon] & chat him up.
If you don't happen to know any of the people he has already been talking to, then have a friend play pointman & get some info as to the whys & hows of him being there.
4) Don't like the 4th grade note passing idea above?
Then just suck it up, walk up to him & be yourself.
Remember - he is also repeatedly in a bar that caters to CD's & I'm guessing GLB as well?
So it comes down to M.A.D. or Mutually Assured Destruction.
He will most likely not out you [to mutual friends] for fear of being outed himself.
Something to remember as well.........
He could be a fellow closeted girl getting his feet wet & checking out the scene before coming out.
Bet you though I forgot about #5 huh?
5) If you know he is there on certain nights take a nite off sort of speak & go there in drab.
It will make talking with him easier & lessen the shock value.
And if he is there for reasons other then CD'ing he won't know about you upfront.
