My children were students at a local elementary school affiliated with the church we attend. My company does the heating service for the church and school. For years, a custodian, who we simply called Lou, worked at the school.
He spoke in broken English with a thick accent. I used to refer to him as the Heat Tyrant because he would shut off the boilers as soon as the school warmed above 60° F or the sun peeked from behind a cloud. He did the same for the church and rectory where the priests slept and worked.
