"If I walk out onto Zabar's floor and I can see my shoes, it's not busy enough."--Murray Klein, former partner at Zabar's, the New York City deli/emporium and retailer extraordinaire, who died yesterday, quoted in a New York Times obituary. Klein, who also loved offering popular loss leaders, said of the housewares hung above the sales floor, "I do a million dollars a year off the ceiling."
