This might sound funny, but kindness got me extra attention and care from the crew. Flew YUL-DOH-YUL recently in J-Class and on the YUL-DOH sector, I was just being myself, to which the crew remarked "Oh, you seem extremely cheerful and very kind to us. I'll ensure I don't keep you waiting for food or anything that you might require." and I got an extra set of pajamas and amenity kit which was pretty kind of them and they voluntarily offered to take pictures of me in my suite when they saw me taking selfies and offered a visit to the cockpit after arrival in DOH.

may sound like QR SOP to keep the guests happy but I guess it worked,, since the entire encounter made me happy??
