oh yeah, nothing worse than obvious phone zombies taking up valuable real estate on the dance floor. I just make sure my arms are nice and swingy which creates a little room around me and people who get too close (due to their lack of spacial awareness) they get a gentle bump and most of the time are actually cool about letting me dance. Some people act real indignant that I'd have the nerve to slightly bump them. One guy didn't get the idea so I literally grabbed hima round the waiste and put him over to place where he wasn't getting in the way. Not in a violent manner but more like guiding him to a place he wouldn't be annoying those who were actually there to dance. Ended up being a pretty funny reaction.
