Great that your brother in law wasn't called out in the end.
Yeah, he was called, but was able to come back for the meal and was meant to head back in after two hours, but another doctor arrived. It is rare that he is able to be there the whole night, any night.
That's tough...
I used to be on call for my Engineering role too, 24 hours a day for a week every 4 weeks for over ten years. It's great to not be on call any more now I must admit.
Sorry for delayed response man, somehow missed it.
