Some folks just have a more intense fear of germs. At work we were temporarily relocated due to renovations in our office, so we didn't have a kitchen. There was a kitchen available 4 floors up. First day I went to fill the kettle and filled it from the bathroom sink (private staff bathroom).
Horrors! "You filled the kettle with water from the bathroom????"
I replied "Yes, but not from the toilet. By the way where do you brush your teeth?".
From that point on any time I wanted the kettle filled, I only need to pick it up, and someone would take it from me and go to the kitchen 4 floors up.

Okay then, that worked out great for me.
