So true turpsy, your article reminds me of a doctor that I work with every now and then. He comes off as very mean and insensitive and he can be. When he is working all he cares about is getting it done in a timely way (he is very good as well) and that means everyone on his team must be competent. Long story short, he is one of the best and timely doctors. If I needed to I would choose him to perform my exams.
Thank you for sharing this little story. I am sure we all have people we prefer in different fields because they have shown enough competence.
