What is it like to work as a civilian?

I joined the military after high school, and before that, I worked at Arbys and did some landscaping under the table; this is all the experience I have as a civilian. I understand that all work places are different, but how relaxed is it in general? Like, will your boss flip out and punish everyone else if you are late a few times, or forget to shave a few times? What happens when you want to go to lunch? Can you socialize and stuff?
