Flying IST - YYZ yesterday. I was wearing a (rare for me) suit jacket. I hung it on the coat hook in the pod, but was never asked if I wanted it hung in the closet. I noticed that everyone who left a jacket over the edge of the pod, or tossed in the footwell had it picked up and hung, but anyone using the hook had it left. I eventually asked to have it hung up when the meal service started. I'm not bothered by this at all, but wondered if there is some secret code involved, or just the way this was handled by this particular crew?
