one reason bottles should be washed at the drink dispenser and not at home:
a lot of people do use those eddie bauer plastic bottles or even an old poland spring whatever bottle for water over and over again... but that's water. it's convenient - you don't have to wash the bottle that often - just rinse it and fill again - whatever, wash it every once in awhile - but it isn't totally necessary. no one wants to wash a thermos that contained sticky sugar drinks after a long day, let alone carry it around. the ony demographic who consistantly use their own personally drink recepticles are babies and their bottles - mabye look into why and how, etc.
