Last month was flying FCO to ATL in D1. Prior to the door closing, a man in casual clothes made several trips up and down our aisle to the front of the cabin. I was in 7A. On his last trip back and while approaching my seat location, the head FA said to him “you are here on the weekend, that’s dedication”. I stuck out my hand to shake his and he said to me “have a great flight”, he got off the plane and the door closed. When it was time to take dinner orders, I was the first one in D1 who was asked my meal preference. Same thing happened for pre-arrival meal. Thought this was odd but was not complaining. Prior to landing the head FA asked how I knew the FCO station manager. Obviously I didn’t, told him so, and the look on the FA’s face was priceless.
