OMG! Who is pooping into the Drink machines at Fast Food Restaurants ?

Okay, I am NEVER ordering another beverage at a fast food restaurant again. On the CBS news tonite they had a story about the nasty stuff that was found in many soda machines at self serve AND employee dispensed drink machines all across the USA. Hold your stomachs, but they found fecal matter, e coli and the bacteria that causes meningitis. The reporter claims that it is due to the lack of maintanence on the tubing in the machines. The machines are supposed to be cleaned once a month, but apparently they are not. But even if the machines aren't being cleaned once a month, how does the fecal matter get into it? There's only one way that I can think of. EWWWWW!!!!!! Okay, I just threw up in my mouth on that one. hahahahahahahaha
