Re: Most inconsiderate
I think, considering the cramped conditions, you were well within your rights to call that person out.
Having once worked in a similar situation (minus the national security implications and blessedly only for a couple of weeks), we laid down some ground rules at the start, and it made the entire experience much more enjoyable for all involved. Saved the smoker a packet as well, since being forced to go outside for his smoke, meant he cut back. At least until the after work trip to the pub..
