Interesting that none of the pro-smoking people are being chided with “The plural of anecdote is not data”, as I was earlier, twice. 
You asked if anyone had seen something. That is asking for an anecdote.
DianaG made a generalization about non-smokers being likely to ask smokers to stop.
That’s where quoting is helpful. It prevents people making the irrational assumption that a post is replying to the one directly before it, if indeed it is not replying to that post.
Sorry, I’ll try to do better next time.
