Concurring Opinion by
Mr. Justice Roberts:I concur on the ground that appellants have failed to adduce evidence from which a jury could reasonably infer that appellee did not exercise the requisite degree of care in maintaining, in a safe condition for its business visitors, the passageway in which appellant-wife fell.
Appellants had the burden of establishing that appellee failed to exercise due care in ascertaining the existence of the refuse which precipitated the fall and in warning of or correcting that condition. See Markman v. Bell, 285 Pa. 378, 383, 132 Atl. 178, 180 (1926). Giving appellants the benefit of all favorable testimony and every reasonable inference of fact arising there*235from and resolving all conflicts in their favor, Penn v. Isaly Dairy Co., 413 Pa. 548, 198 A. 2d 322 (1964), this burden was not met and a nonsuit was properly entered.
