I always say thank you very much on the way out and also once asked the First Officer who had come out to say goodbye to the pax if he had landed the plane. He said yes and I told him it was a superb landing. He looked please as punch. I am doing a lot of volunteering for St.Johns Ambulance at present ie., vaccinating and post jab observing etc., and it is so nice when people you have just jabbed or looked after thank you and tell you they appreciate what you are doing. It means much more than any gift.
