First Rant: Invisible Walls

I wasn't going to say anything till I got more work done, but the stream of coughing has prompted me back.
I've recently returned from a trip to Japan, and I'm currently suffering from second-hand smoke. It boggles my mind when I think of the lack of awareness or indifference to the effects of second hand smoke. I can partially understand in adult establishments like bars (although I knew if the same establishment were here, I would choose not to go), but in family restaurants...the use of the invisible wall to separate smoking and non-smoking sections...not cool, and hazardous to your health (as my literally aching lungs can atest to).
