Im somewhat confused. If the passenger is not stopping your exit from your seat, i dont understand why this bothers you. There are far more annoying things on planes, for example, when someone uses your chair to get up and shakes it and wakes you up.. if their feet is protruding onto your arm rest.. and one of the worst ones.. being sat on a row of three on the aisle where the couple spend the whole long haul flight making out.
You lot need to sit in economy more often on long haul flights if you think that putting your shoes on the bulkhead is bad manners haha
