You'll just be so glad to be off the aircraft that you won't even care about potential contamination. ;-)
Seriously though, their cabin crews are such a pain in the a** that it just gets aggravating after a while. And they're that way to their frequent business fliers.(Most of whom would be on another airline if they had a choice. Lately I find Continental to be above average).
I'll just behave like I did when I was a temporary and worked at various really putrid law offices in Tampa-town, including McLawyer's Holland & Knight. He ruined them you know. I will just tune it all out coming and going. LOL
