Brazilian workers have this great way of napping during lunch break. I've thought of picking up the style. These guys are great examples. Just find a flat-ish area, maybe a piece of cardboard, take of your shoes, and snooze. Snoring, drooling, looking like you're sleeping on the job, don't worry about any of it, because as much as we see city workers asleep on the side of the road, it must be a job requirement.
