lol, I remember one time I went to Portugal or Italy or somewhere really close but anyway, for some reason, it was a cheap flight company, instead of putting me and my gf in the same row, they put us separately, so we sat at the back, each of us in the last seat of a row, so out of spite we pretty much ****ed off the flight attendants who were always trying to get in the back for the kitchen or w/e , by kissing and constantly talking.
Yes that was a bit of a pricky thing to do, but not sitting a couple together is as well.
I had this happen to my girlfriend and I when we went to Amsterdam. We just sat in our seats and got on with our lives though. No big deal - I can cope with my own company for an hour or two.
