Water? Why buy what is provided by the university for FREE?
I always bring 3 bottles from home in case I want them to drink just because I have them at home. We need to think of the fact that people can always use the water fountains and if they want water at their computer then they can bring something to put water in. If they really want bottled water its like 3.75 for 24 bottles at Walmart.
If there were soda fountains for free then I would say the same thing about that.
