In Lundy v. Groty, 141 Mich App 757, 759-760; 367 NW2d 448 (1985), the Court stated that the duty owed by a possessor of land to a business invitee is as follows: A possessor of land is subject to liability to physical harm caused to his invitees by a condition on the land if, but only if, he: a) knows or by the exercise of reasonable care would discover the condition, and should realize that it involves an unreasonable risk of harm to such invitees, and b) should expect that they will not discover or realize the danger, or will fail to protect themselves against it, and c) fails to exercise reasonable care to protect them against the danger. This duty has been interpreted to mean that "a business invitor is required to take reasonable measures within a reasonable time after the accumulation of ice and snow to diminish the hazard of injury to an invitee." Id. at 760.
