Make-out parties at work

In an earlier post, I mentioned how I saw my boss brushing his teeth during the middle of the day. Over the past week or so, I've noticed more coworkers doing this and on a fairly regular basis, mostly before meetings. So I'm as aware of bad breath as the next man, but unless people sit a lot closer at meetings over here than in the U.S., there's only one other logical conclusion I can draw about all this teeth-brushing... these so called "meetings" are actually just make-out parties. I mean, a one hour make out party in the middle of the day? What middle-schooler could say no? Then again, all of the workers in my office are dudes... nerdy dudes...
