Funny enough. I never smoked, but I often went and hung out in smoking sections outside our work office. I really enjoyed how open smokers were to just random conversations, and the quick 10 minutes of not looking at the screen were typically energizing. Almost like a natural pomodoro work schedule that forced up out of our desks, and then out of our offices.
Socially adroit undergraduates suiting up to exchange dead tree resumes at job fairs in exchange for the URL to online portals can definitely benefit from taking air breaks when/where recruiters do. No need to engage them to unless prompted, it's corporate Switzerland, but there is comfort in recognition on both sides of the booth.
