I've vaped in resturants, stores, hospital, doctor's office, post office and sports bars with no issues. In a restrurant or sports bar I usually tell the waiter or manager about my PV and what it is. If they don't want me to use it (only happened once), I respect their wishes. I don't go back there but I don't make a fuss. I also have a small card I have made up to pass out to the curious because many people want to know more. It is also a big advantage to vape a PV that looks nothing like an analog which is what I do, using a variable volt Darwin.
