A commuting Captain was not wearing [a] mask the whole flight. The situation started when I asked the [commuting] Captain during the flight to wear his mask; his reason [was] because of the open bottled water he was holding the whole flight. When deplaning the commuting Captain approached me before he is about to leave the aircraft and asked me about the wearing of the mask policy and mentioned that I was being [demanding].I do believe that safety is our priority [for] both passengers and employees; and I  believe that the Captain should be the model to all the passengers for wearing the mask in the aircraft; but he is the one who breaks the procedure.
