It amazes me how disrespectful some vapers have become over the years. Very disappointing!
It's not disrespectful if you ask first. It's also not disrespectful if you vape when no one is around (as the vapor dissipates very quickly). Most of the laws with regard to smoking in these areas (like hospitals) haven't been adjusted to include vaping so the worse thing that can happen is you will be asked not to. Fortunately I didn't have to ask, the Doctor and Nurse saw my vaping setup sitting on the bed beside me and said "you know it's OK if you use that in here". Of course I have no doubt that a policy will be made someday soon that will disallow hospital vaping at this hospital and then they won't be able to give me unsolicited permission.
