I would go with bottled water and apparently I do this more often. You know, drinking bottled water has been a part of my life. For example, when I am jogging in the park or after playing sports in the open area, a bottled water is required. Quite user-friendly by the way. Besides, when I am driving on the road, a bottled water is usually with me as well. For my part, I don't trust the water machines because the water in it couldn't be very clean, not very healthy to me. My point exactly. That is it.
