With all due respect, you seem to be overlooking Chris's Olympic-level skill at being banned. He has been banned from EVERYWHERE for a wide variety of reasons. He has been banned from his church, from the Cub Scouts, from McDonalds, from community college, from a game and hobby store, from the Wallflower's heart. Sometimes it's because of tardraging, sometimes it's because of rule violations, sometimes it's egregiously antisocial behavior, sometimes it's undefined assholery, sometimes it's felonious assault. Often it's after a drip-dripping of behaviors that culminates in a ban only after a long while.
If Chris was such a harmless shrinking violet, he would never have been banned from anywhere, ever. Instead, he's been banned from nearly everywhere, throughout his entire life. Chris is shy except when he's not shy. When he's not shy, he flips off cops in public, he screams at children, he does drunken karaoke, he paces and sings loudly to himself at the mall, etc., etc. There are a dozen reasons why he might be banned from the gay bar. Maybe not next week, but eventually. In fact, given his track record, it's practically guaranteed.
