This is generally viewed as inappropriate, Aquaman.
I distinctly remember last interview season there was this guy that always brought a water bottle with him to interviews. Well, at one program (that I won't name), the PD saw this interviewee with the water bottle and said "who's this mother-fu*king high and mighty MS4 think he is bringing water to a derm interview? Is he out of his fu*king mind bringing water in here? Get this son of a bi*ch out of my sight before I puke in my handbag!!"
So, be careful with this hot potato(e).
