I wanted to say that I have been accused of being in the wrong seat on one occasion. It was when I was flying First Class on SAA last December. There were some family friends seated in business who I had seen in the lounge and then went back to talk to during the flight. Anyway I sat down in an empty seat and began chatting. A FA came by with drinks and I helped myself to orange juice. Well she took one look at me and went running off to get help. Well there was a great amount of activity from the galley as that FA explained to the head FA that I had just appeared in Business. Anyway the head FA comes back and says to me that I am not able to sit there. I like Merry know what she thinks, but am going to have a little fun at her expense. Anyway so I ask why not an she explains that this is only for Business Class passangers. I respond with the all to classic, but I just want to talk to my friend. She responds that she cannot let me spend another minute there and I MUST return. I say there is no need to get into a state and I will be happy to go back to FIRST class. I think her face nearly fell off. Needless to say that she was sorry.
On another note I always keep my BP on my armrest as much for the person sitting next to me as the FAs. It has become less of a problem over the last couple of years, but when I was younger I was questioned all the time. Now the only question is am I old enough to drink?
