Its a non smoking enviornment, you should at least respect that..

If it were me, I wouldnt necessarily stop smoking in the place, but I'd at least not bake the place out.. just open up the window and get a decent fan to help guide the smoke you exhale right out the window.

If you've already been warned, I wouldnt think light of it.. they can simply call the cops and get you all busted. So id be careful.
