Have any of you ever considered just politely respecting the wishes of the restaurant and not vaping while you're there? Not everything has to be a power struggle.
That's just fine, but the sign doesn't precisely say "No vaping", does it? It prohibits carrying an 'e-cigarette' in your pocket or purse. Are they going to give me a quick pat down before I'm allowed inside? Nope, when they express it like that, I'm gone. Perhaps, I'll let them know why; perhaps not.
