This is terrible. I should be doing my homework and I just stopped by to check on something and here I am caught reading this thread...

But I'd like to add my gripe:

People who don't clean the sink out after using it. (Okay, so this may be a public confession on my obsessive compulsive behavior.) But why is it so hard for people to dry the sink with the same towel they use to dry their hands? Maybe I need to see a therapist on this but the thought of those water drops drive me crazy. I have even gotten up to check the sink after someone else uses the lavatory just to confirm my suspicions on their character...

Maybe they just need to put porcelain sinks on planes. The thought of water drops on porcelain doesn't bother me... It's just those little drops on stainless steel that get me all riled up.
