Listen, much of what we say in the cockpit is for a$$-covering (as much as anything else) in the unlikely event that something unfortold (sic) happens and the Company pulls the CVR tapes. We can argue until we are blue in the face about what should and shouldn't be said in the flight deck. At the end of the day who cares as long as the lines of communication are clear and effective. If one can't live with saying 'check', 'confirm(ed)' all day long then they are in the wrong job.
