What are some advantages of a drinking fountain?

Some believe it causes wrinkles: http://www.examiner.com/article/reason-not-to-sip-from-a-drinking-straw & some worry about its strain on the enviroment because of people possibly littering with their straw's wrapper and adding to harmful buildup of plastic in landfills due to improper dispoal of straws (trashing it instead of recycling it) though, both of these concerns are easilly dealt with if you do "facial yoga" and purchase only straws composed of recycled materials & remember to recycle all of its components.
