Funny, my wife is primary care yet does on call via answering service. You clearly don’t know what you’re talking about.

Funny, I chose that gall bladder example precisely because I had it happen to me.

In addition, I had something similar happen where I wound up needing Interventional Radiology to insert a drain--again wound up waiting from Friday to Monday morning.

I'm sure some of those doctors were "on call". However, nobody was calling them in unless I started dying.
