The old lady was running a bakery. Saint Peter was a wise saint. He had travelled and preached a lot so he was tired and hungry. He had arrived at her door for some food. Still the lady made him wait for the cake for a long time. Every time she tried to bake too small cake but unfortunately the cake often seemed to her of a bigger size. The old lady did not want to share the cake of this size with the saint. At last, the saint grew angry and cursed her. So, it can be said that her greed had no limit.
