As a common carrier, Defendant owed Plaintiff "a duty to exercise the highest degree of care." Katamay, 289 N.E.2d at 625; Manus v. Trans States Airlines, Inc., 835 N.E.2d 70, 73 (Ill.App.Ct. 2005). "As a result of the unique control it possesses over the safety of its passengers, a common carrier owes its passengers the highest degree of care consistent with the mode of conveyance adopted and the practical operation of its business."

Generally, a circuit court's prompt action in sustaining an objection cures any prejudice resulting from an improper comment. Manus v. Trans States Airlines, Inc., 359 Ill. App. 3d 665, 670 (2005). In addition, the error is often cured even "if the trial court does not rule on the objection, but rather merely instructs the jurors that they should rely on their own memories of the evidence."

During oral argument on this appeal, YMCA acknowledged that a non-IPI instruction may be given on certain occasions, including where the IPI instruction does not accurately state the law. Manus v. Trans States Airlines, Inc., 359 Ill. App. 3d 665, 668, 835 N.E.2d 70, 73 (2005). YMCA also argues, and we agree, that the two IPI instructions given by the trial court sufficiently stated the law.
