Respect, just respect. I don't know for a fact, but I don't THINK
vaping harms bystanders. However, I don't blatantly go about any of my business like I'm the only person in the world that deserves special treatment. Do I vape in public places? Yes and no.
I don't openly vape when I'm shopping--at the grocery or anywhere else. I vape in restaurants that allow it. The places that don't allow it usually have private restroom stalls that will do for a few quick vapes, exhaled into my shirt instead of upward for everyone to see. Or I can always go outside.
I have seen a couple of people vape at our Wal-Mart. One guy who was with his wife was taking discreet toots (I wouldn't have noticed him at all if I weren't a vaper, too). I didn't see anything in the air, but since I was fairly new to
vaping at the time, I recognized that he was using an e-cig. I stopped and talked with them for a minute. He never smoked, but he was trying to ditch oral tobacco (can't remember now if it was snuff or chewing tobacco).
Another young-ish guy ( maybe in his late 20s, early 30s) in a wheelchair, in the produce department, being pushed along by someone else--I noticed a faint wisp going up in front of him, barely noticeable. As I inched closer, I saw that he had a mod and a topper with a glass
tank (far ahead of the evods I was using at the time). I wanted to pat him on the back, have some conversation and offer encouragement, but I just let it go.
There are lots of ways to do things in this world and lots of ways around situations. Being pushy about isn't always the best way.
