thoughtless behaviour doesn't only happen in coach. Two years ago my family was settling into our bulkhead seats right behind business class on an Air Canada flight from Munich to Toronto. The couple seated behind my husband and I removed their shoes and put their feet up on the back of our headrests as soon as they got to their seats. We were worried about spending several hours in their immediate company, but noticed they were hassling the flight attendants about upgrades. They did get upgraded, and moved forward to be replaced by some quiet students who kept their shoes on. Every time I think of paying the extra to fly business class, I remember that couple.
