Do what you normally do and ignore the whole professional thing. Its no big deal. Does no-one in your field of lobbying have a sexual relationship with another one in that field? I find that hard to believe. How do you think these relationships started? Do you think that if you are in a office building... That in the complete building there is not one room that has seen some kissing or after businiss hours sex?
Just run game and ignore the fact that its in a professional setting. Obviously you must extract the targets to a more romantic location... If she says yes. Its on.
I work as a marketeer and one of my favourite sarging places are exhibitons. I completely ignore the professional relationship and start gaming. OK, more subtly than you would do in a bar, but I'm sure you understand. Girls love it. Exhibitions would otherwise be boring for them
But honestly, it is harder. Girls in a professional settings have a bitch shield with extra camouflage. So stop overthinking this and start lobbying for your cock for a change
