My take on all this is that any company that rents or leases a portion of a building only can control the inside of that building and not the public area outside. If they have an area outside for their business, then yes, they can regulate that area as well.
No company that doesn't own the parking lot can tell you or me that we can't so something out there.
I worked for an medical
insurance company. they told us that we can not smoke or
vape on their property. So we all went out to the sidewalk and smoked/vaped. They didn't like that and tried to stop us from being on the sidwalk and told us we had to go across the street.
I, very nicely, explained that the public sidewalks were just that. Public. And they could not dictate to me what I did on public property. I am obeying the company rules and am not on their property. They finally backed off.
Basically I think we as vapors can do pretty much what we want to. We are not smoking cigarettes, we are using water vapor. Companies that ban electronic cigarettes are just ignorant and don't know any better.
I live in Henderson, Nevada, and I vape everywhere. No one has ever told me I can't do that. I have respect for people and the places that I am at, but if there isn't a sign that says "No Electronic Cigarettes", then I vape.
lol just my 2 cents......
And peterforpats, relax and have a smoke....err.... vape. Everyone is entitled to their opinion. I respect yours, but you seem to be trying to force it on us. Relax

It's all good !!!
