Stupid nose, fail me now!

Ok, unfortunately my job requires me to have constant contact with those dreaded other humans beings...there's never a dull moment. Most days I manage not to throw myself out of the nearest window. However, today I almost did...the reason you ask? Two words: Stinky people!
Why do they exist?
Can they not smell the rancidness of themselves?
If your "personal perfume" is so powerful that it fills an entire room and lingers for the remainder of the day, then you, Sir/Madame, have a problem!
