My tap water? You didn't mention me or my tap water. Personally? I drink tap water almost exclusively, and if I ever get a plastic bottle I reuse it (even beyond a safe amount of times) then recycle it. But your original comment was pretty out of pocket towards OP. Lot of pretentious assumptions.

Again, you don't know someone's personal situation. Sure, if you're in a place with good tap water and exclusively drink bottled water because you have the money to do so, that's not really great. If you grab it when you need it either for emergencies or because you needed it at that time and to use later to refill and recycle, then so what?
