> "I can't stay late tonight" is fine unless contractually you are on call. This is potentially a reasonable point. If the surgeon can't make a compelling case to the on-call anesthetist that the case needs to be done, then the anesthetist present has a reasonable argument. That said, I've found that day shift staff may well stay late to handle a case they had already prepped for if that would prevent an up-prepped on-call from having to come in an hour later.
