Possible Scenarios:
* Misspelling or Misremembered Title: There might be a misspelling in the title, or you might be remembering a different title or story.
* Local Folk Tale: It could be a regional folk tale or a story shared within a specific community that isn't widely known.
* Personal Story: Perhaps "Mere Master Sahab" is a personal story or anecdote, a memory or experience that you're trying to recall.
To help me understand:
* Can you provide any additional details about the story, like the setting, characters, or general plot?
* Do you know who might have told you the story?
* Are there any other keywords or phrases you remember from the story?
With more information, I can hopefully help you find the story you're looking for.
