I've only seen this on patios, but I could be wrong. The absolute worst is when some guy lights up a huge cigar right next to your table. That happened to us at breakfast on the patio deck at Holland House a few weeks ago. The dude had no clue how bad it was to deal with that smoke. The breeze helped a bit, but it was still very strong. I was thinking to myself "C'mon man, do you really have to smoke a cigar while having breakfast?" If this happened indoors somewhere my wife and I would move to another table if possible.
