Being deployed and working 15 hour days 7 days a week makes it so that noone really cares if you're gone for an hour (at least here in my unit) so I have the luxury of taking my time with a pipe. Reading the "20 minutes?!?!" thing made me realize how very priviliged I am for having that luxury.
Where I'm at currently, as long as you get done what you need to (as well as getting a head start on other things) nobody really cares what you do.
Transitioning to civilian work will be a rough transition on me some day.
When I'm cramped for time, I use a MM natural, they're fairly little and hold about a 10-15 minute smoke. I use them for aromatics as well to keep my briar dedicated to Latakias.
