I'm going to get flak for this, but oh well. Here goes.
Just to play devil's advocate for a minute, the fact that the policy changed at work does suck but it is their power and they have the right to choose whether to let you plug in or not. If an employer starts getting complaints from other employees, they have to make a decision. Granted, from our point of view, they should have explained the situation better and tried to diffuse the situation rather than just shutting down the person charging, but honestly we don't know the full story here.
Remember, as Leaf owners we don't want to get that "Pious" label that people were hanging on Prius drivers back in the long long ago. I don't want to be snubbed at because I'm "one of those self-righteous EV nuts".
On the same thread, let's consider the outside point of view of the dealership incident. One employee makes a mistake, had a bad day, might be an a-hole anyway, who knows, but gets a little hot headed that someone shows up and is using "their" charger when they haven't given any business. Now all of a sudden there's a "mob" of other EV nuts that are calling in harassing the dealership, submitting all kinds of complaints via corporate, and all else. My first reaction might be "geez, what a bunch of whining a-holes these Leaf drivers are. Our dealership doesn't need this flak, maybe we should re-think this whole program..."
I'm not saying Casey or the employer was in the right. And I agree this was a bad experience and I certainly would consider this event if I were in the area and was looking at buying or servicing a vehicle, but let's also try to remember to avoid the mob-mentality and try to not make a bad name for EV drivers.
