Maybe, the house elves stay busy in the kitchen, just as most cooks & 
dishwashers do in muggle schools. You see the janitors mopping up but 
you rarely see the cooks & dishwashers unless you go back into the 
kitchen. 

Fred & George have seen the house elves because they have sneaked 
down into the kitchen late at night. I would know if I had house 
elves, cuz I am a late-night-kitchen-sneaker-into like George & Fred.
