Isn't there a statewide smoking ban in WA? So how is it that a private property owner doesn't have the right to allow a legal act (smoking cigarettes) on their property but can at the same time 'exercise their property rights' by telling you that you can't do something that's legal? Statewide smoking bans relinquished property rights.
Please note that I wholeheartedly agree with a private property owner's right to disallow whatever activity/individual they please on their privately-owned property. I just find it incredible that so many of these private property owners didn't throw an absolute fit when statewide smoking bans were being proposed...whether they were malls, taverns, restaurants, or tire shops. Most business owners probably thought, "Oh, I don't care if they ban smoking on private property (workplaces). It doesn't affect me." Well, it does. It brings the whole issue and right of property ownership and choosing what acts you will or will not allow on your property come into question, and thus, degrades property rights in general.
This is what happens when you eff with the Constitution, which is what smoking bans did. Nothing makes sense, and rights are slowly (or quickly) eroded because precedence is set.
I'm sure that the mall management decided not to allow the use of e-cigarettes because they don't want to deal with the constant complaints from their patrons thinking that people are smoking. As e-cigs become more widely-used and less 'scary' to the average person, I think you'll see a lot of this sort of thing stop. But maybe I'm just being optimistic. This is why I think we need to vape in public whenever possible (without flaunting it, of course, and in the right situations) and be prepared to explain it. Yes, this can be a PITA, but until more people some to an understanding, this is what we're charged with.
