Thread drift.
In the late 1970s I was working at Muscat.
There were 2 or 3 TMAC and Tradewinds CL44s night stopping most nights. In the morning we would see them lined up against the sunrise. I noted that the TMAC ones always had the props dressed whereas the Tradewinds ones were all over the place. TMAC had a station engineer and I mentioned one day that the other lot were lazy and couldn't be bothered to park their props. He said they did but over night he would move them just to wind them up.
Happy days.
