How often do you sleep at work?

Whether in office, or when working from home, do you ever sleep at work? If yes, how often?

I have had quick 5-10 minute naps many times at my old in-office job. It was a very small company. Some days there were only 2 of us in one of the cabins, so it was pretty easy, she was okay with it. Sometimes, if she had to ask me something and found me taking a nap, she was like, nevermind, you can go back to sleep. Since she sat near the door, she would alert me if one of the bosses is coming around.

Here's a meme, btw...
