I'm not saying they are lazy. I'm saying they are extremely relaxed, like there's nothing to do. 90% of the show is doctors talking about personal stuff, bullying other doctors, dealing with feelings (theirs and others' people) and doing anything else than treating people. You're probably right that there's time for that in a workplace and even with people collapsing in the waiting room they have to stop and have a personal conversation with someone every now and then. Maybe they are treating people off camera and the show just focuses on other things. For me this focus was unbearable. It made it look like no one is being treated while doctors move around slower then me on a coffee break.
It could also be that I'm used to ERs in Europe. Here when I go to ER doctors sit in their rooms and people get assigned to a room. So doctor will see one patient after another without walking around, wondering what case to pick next and chatting with people all the time. For me that's how hospitals work and The Pit just looked like a disorganized mess to me.
