When you put down a buck or two for bottled water, you’ve wasted money. What you get in those bottles is sometimes tap water, or maybe filtered water. Either way, you could have avoided that purchase by carrying your own reusable water bottle from home — you can filter it there if your tap water is at all funky.
Or, drink it from a fountain. You’ll save the environment from one more plastic bottle.
