Chris,
I'm not sure if being hit on is your first priority, I keep smiling to most people but inside I'm just trying to keep control of my heels, my venue has wheelchair access ramps, they are far trickier to deal with than stairs.
It's funny how the concern what other people think fades away, there is such a cross section of Cders you begin to realise that you haven't done a bad job with your clothes or makeup. When I think of it like that it must be a similar feeling GGs get when they go out !
