I look at it this way, I never smoked while going up and down the isles of my local hardware store, or my grocery store. But then I've grown up in states where smoking was banned 100 feet from any doorway, window (that could be opened) or air conditioning intake unit. Why would I vape while walking up and down the isles of my local hardware/grocery store? Parking lots are a whole 'nother story. But again I live in a state where smoking on "ANY" hospital owned property will get you a ticket. They are starting to include e-cigerettes and pvs in this category. Honestly if I can't wait till I left the parking lot to vape then I seriously need help with my addictions to nicotine.
