Just to clarify a few things:

My main concerns are:
- I won't buy my 2L+ a day from a vending machine...I'm not made of money.
- I'm concerned that the filter in the cooler is filled with nasties and needs replacing
- I KNOW the bathroom is filled with nasties but I'm unsure of the chances that could get into my water if I filled my bottle there.

I don't get sick easily but I'd hate to catch something when it was preventable.
