There is never a good reason or acceptabe basis to be rude, inconsiderate of others and behave as described above in this topic.
The fact that a pax has status on Northwest or any other airline does not give them permission to be obnoxious or inconsiderate to other pax.
Those of you that disregard the welfare or other pax have lost your American values/common decency or compassion for pax that have disabilities or handicaps,
Try and show common curtesy.
