They were not very attentive. Came through twice to see if we wanted water, that was it. Week on coffee, asked twice and said only with breakfast and there was about an inch of coffee in my cup, that was it. Maybe if they weren’t playing cards, we could hear them shuffling, they might have given us a little more attention. I don’t ask for much but might as well been in economy. Won’t fly with you again after this trip. KLM much better 🤷‍♀️
