If you had a serious basis for your argument, you could probably drop the straw man, since I'd wager that above 99% of the vapers who think your attitude is rude, selfish and counterproductive, will quite happily vape more or less anywhere where they're allowed to - which includes many public spaces.
How many posts have you seen where someone said: "You should only vape at home, when nobody is looking"?
I have seen vapers, in these discussions say, "this is why I only vape in my home and my car" or something along those lines. And then proceed to make points about how it is inherently disrespectful to vape in public places.
As I've seen many of these same people make their own personal exceptions of where it is okay, for them, to vape, then of course their position becomes hard to reconcile. As I am addressing this to generic mutant, I do believe I've seen a previous post from you somewhere on this forum about a place in public that you make exception and allow yourself to vape. Perhaps I'm mistaken, and feel free to correct me.
The point I feel I'm clearly addressing is the idea that vaping in public is inherently disrespectful, unless you've been given the okay. Even then, for some, it would still not be okay, because property manager may say yes, but non-vaper may not know that policy even existed until that fateful day comes about when you are vaping, and they are now, for first time seeing that occur.
I believe, though not sure about this, that most people who enter into this discussion and are on the side of "please don't vape in public" do agree that secondhand vaping poses no significant risk to all other persons, with possible exception of children. So, to be clear, I am saying that the opposition I (and others) have on this issue isn't the health concern, at least here on a vaping forum. Instead, it is the idea that vaping will be, perhaps already is, labeled a public nuisance. And then if we have the story of militant vaper who blows huge plumes of vapor while seemingly not caring about anyone around him, including kids, we (who are in this discussion) are foremost dealing with that type of vaper. I haven't seen that vaper, even in the mirror, but as others have seen it, I do believe it is possible he/she exists. IMO, that isn't a vaping issue, but a behavioral issue. I also think of all the people everywhere on the planet that do vape in public, that type of vaper is in an extreme minority. But play that card, and be on the side of "no vaping in public" and you've just played a golden card that makes it challenging to defend public vaping.
Yet, that isn't all we are dealing with in this discussion. For if it was OP's example would've been met with universal approval of, 'really, you did nothing wrong.' Instead, as usual, this discussion spun into idea that everyone who dares to vape in public, especially if they have not been explicit approval to do so, is engaging in inherently disrespectful behavior. Which is what I feel myself, and others who tend to support the idea of 'vape everywhere' have to contend with here on a vaping forum.
We are treated as the misfits of the vaping community and shamed for our choices, regardless of circumstances and situation that we present, as OP presented one where I cannot see the nuisance that is plausible in what was presented. But keep hammering away on the public nuisance message, regardless of circumstances, and I am certain that at least some minds will be changed about public vaping. Though IMO, and again the position that I understand CASAA to be coming from, this continual hammering of vaping in public as always disrespectful / selfish, is carrying the torch for those who wish all of society would shame vaping. Especially public vaping. But as the industry does exist with certain aspects that make it an easy target for those prone to shaming users and anything that could plausibly be used by kids, it is also feeding the idea that vaping itself is inherently disrespectful, regardless of where it is done.
That all this needs to spelled out on a vaping forum actually humors me, especially given context around politics of smoking. But hey, if you truly believe the anti vapers will stop right after vaping is banned from certain indoor places and that will be the extent of their fight, then I'm not sure what else there is to say.
Part of this issue, IMO, has to be us drawing the line in something that may be entirely unrealistic over the long haul, but positions the vaping community for what will be legitimate reasonable regulations down the road. If smoking is at all a roadmap of what's to come, and we are willing to draw the line with 'better to not vape in public at all,' I would say be prepared to give up more. For even a portion of the vaping community will go along with idea that flavors aren't necessary, nicotine over 12 mg isn't necessary, vaping in your car isn't necessary, vaping within 2 miles of a school isn't necessary, and vaping in your friend's house that currently allows it, is not necessary.
