Shag break

It has been pointed out to me that the goings on highlighted in that last post did not involve doctors, and that this might be because doctors have reserved car parking spaces in the hospital, making such activities impossible. I don't think that is the reason though. The giveaway is that the staff involved are engaging in these activities in their break. What the fuck is "a break"?
Still, the next time a nurse excuses her lack of knowledge of what is going on on her ward with the phrase "I've been on my break" I will look at her in a new light.
