Water Fountain and Restroom

Okay, so this just pop out from my mind a few days ago when I came out from the restroom in Caldwell. Why you can (almost) always find a water fountain near the restroom exit? Restroom, bathroom, toilet, water closet or whatever you called it.. it's not really a hygienic place to drink something right? Okay, you can say that it's outside - so it should be okay. Wrong! So many times I was drinking from the fountain, and suddenly someone came out from the toilet - releasing all the "fresh" air through the door. Right in front of my face! And even if its not releasing an "unpleasant fragrance" on daily basis, how could you drink water tap while seeing a restroom with all the "interesting activities" inside? Oh well, maybe it's just a cultural thing..
