I liked your comment, but I also could see this particular incident as a potential "dual user" where he/she did use an E cig and also had a few cigarettes.
Except she insists (she contacted stevevapes.com - if you click the link I posted for the follow-up story) that she was never smoking in the hotel.
Here is her email to him:
Good morning, I found your site and I am the person you quoted as being fined the $250 at the South Park Marriott hotel in Charlotte, NC.
You indicated that I may have been smoking a regular cigarette and was just trying to cover up? The answer to that is No, I was not. I suspect that I was reported by room service as I had my ecig laying on the bed when they entered to deliver breakfast, and of course to the untrained eye..... you can decide on that one! I did not have housekeeping while I was there as we were there for a wedding and needed all the time in the room to prepare for the wedding so any other type of suspicions by the Hotel are unfounded. The only excuse/story the manager of the hotel gave me was that housekeeping "smelled smoke in the hallway". As everyone knows hallways are public places used by all the hotel guests on that floor along with anyone else.
Marriott's final email to me said that they are going by the same rules as airlines, if they don't allow e-cigs then neither is the Hotel, the Manager also boasted how users of e-cigs in a public area in the Hotel had been asked to leave!
