In Fortgang v. Chase Manhattan Bank, 23 N.Y.2d 895 (1969), the lessee provided mats for the floor on rainy days as a safety factor. On the day of the accident, which was a rainy day, the lessee's porter had put mats in the lobby but had left a space of about a foot and a half from the elevator door not covered by mats. Plaintiff stepped on floor that was not covered by a mat while getting into the elevator and slipped and fell. The Court held that an issue of fact was raised as to whether the building lessee maintained properly placed mats on the lobby floor during rainy weather and kept the uncovered areas free of excessive moisture.
