* If you are using a '''large bottle''', you should:
** Also take '''disposable cups'''.
** If asked to '''you should only refill a person's individual bottle/flask '''/flask, only do so if you can be sure that the mouth of the large bottle does not come in contact with the mouth of the bottle being filled'''. (This will be contaminated with the person's saliva).
** Wide-necked flasks can be refilled, but it will be difficult to refill a small disposable bottle safely.
