It really isn't that big of a deal, even though it does come off as immature.
A professional would handle it like this:
1) He or she wouldn't choose to use such phrasing himself or herself, but also won't shy away from being firm and asking hard questions if they need to be asked.
2) If somebody else chooses such wording, the professional will engage his or her thick skin and ignore it, instead focusing on the parts that actually matter. It's resolving the problem at hand that's truly important, not wasting energy getting worked up over phrasing that somebody chose to use when describing the problem.
