I haven't said anything because on one hand it seems stupid, the guy is standing on his patio, minding his business.
It's just the principle of the thing - do you get to blow smoke around everywhere, even where others don't want it, or do I have the right to enjoy the air in my own apartment w/o running around to shut the windows?
ps - With all that barbeque smoke, you were probably blue in the face from the fumes. : )
To tell you the truth the barbecue smoke made me salivate----it always smelled enticing. I closed the windows so it wouldn't get all through the house. They were a nice couple and I never would have even considered saying anything.
You live close to people you have to put up with inconveniences---or you move to the country.
