I vaped in a casino restaurant the other night (at the bar), but asked the bartender first. English was obviously not her first language, so I explained that it wasn't smoking, that you couldn't smell it, and that it wasn't harmful to others. I puffed on it, blew out some vapor, and asked if she could smell it...she said "No, but you're not supposed to smoke in here." I explained that as of yet, there are no bans on PV's here, but that if anyone complained, I would quit immediately. Not only did anyone NOT complain, I had a bunch of people interested and asking questions.
Then, on the boat, where smoking IS allowed (and I could barely breathe), I sat at the Blackjack table and vaped away. There were other people with me who were smoking, and an elderly gentleman who was smoking like a freight train. Again, I got lots of questions, and attempted t0 explain about PV's; and a lot of people told me how grateful they were to not have to be at the table with a bunch of people blowing smoke in their faces.
I also vaped at a local restaurant the other night--made sure to okay it with the owner/manager first, and was so happy not to have to go outside with my friends for smoke breaks.
I've also vaped discreetly in Wal-mart and Target, without complaints. However, I was a bit more stealthy about it there, and didn't blow out the vapor out in big clouds, but inhaled the majority of the vapor and kept the 501 kinda hidden.
Vaping rocks!
