For the most part, I vape everywhere. I don't go out of my way to get noticed.
When I'm in a store, I will vape in the isles, but I don't while at the check stand or standing in front of an employee while talking to them.
While in a restaurant, I don't wait for the waiter/waitress to come to the table then vape, I vape in between.
At someone's house, I will ask and abide by their decision. My family and friends that know what it is, don't have an issue.
Over the last year, I have been questioned in stores & restaurants, probably 4 times, but not denied after explaining to them.
Most of the time, I don't get a second glance. The last public place I vaped at was sitting at a bar having a beer with my PV sitting on the counter. There were 2 bartenders and less customers and didn't even get a look.
I vape when I want, but I don't do it to get noticed, so I don't go out of my way to make sure people see me.
I will also be discrete when I feel I need to, whether real or imagined.
