Culture is what you make it. I'm a big believer in power naps, and I used to work at Google. This was a while ago and there were no nap rooms in my building, so I just lay down on a couch and zonked for twenty minutes every afternoon. This was in a hallway with dozens of people going by. Never any problem. (Of course, this only worked because I didn't mind the noise, but with more effort I could have found a quieter location.) Obviously, there are plenty of more traditional workplaces where this wouldn't fly. But at most tech companies, the problem is not that you wouldn't be allowed to nap, it's people not realizing the value or feeling too silly about it.
