My DIL has asthma and we don't smoke around her as a curtesy to her and her health but she has never asked us not to smoke around her. My stepson is your typical anti smoker.
I would never smoke around someone that I know has asthma or any other problem related to smoke..............
I'm 44 years old and have only known 2 people in my life with asthma that are now adults.........both of them are smokers.
I grew up in NYC and never met anyone with asthma until I was in my late 20s (the 2 mentioned above) and living in Delaware. After that it seemed that I was forever meeting people that had children with asthma, and they were all non-smokers. They were also fanatics about cleanliness - I mean, eat off the floor clean types. Drip something on the counter and the antibacterial wipe came out type.
I truly believe, and there is much evidence to back it up, that the antiseptic lifestyle so many people are choosing is not healthy. I had my daughter much later in life than most people I knew - but I guarantee they would be appalled that my attitude about her going out and making a mud puddle and jumping in and getting covered in mud is - OK strip down and get in the tub. she's a child, she's supposed to play and children get dirty - big deal.
Sorry for my rant - but the same kind of people that would deny a child playing in a mud puddle are the same that will deny a business owner making his own decision about clientele.
