Refund: A farce in one act by Frigyes Karinthy

Author bio - https://en.wikipedia.org/wiki/Frigyes_Karinthy

One of the funniest stories you will read; I had this in my English class in the late 80s.

I had forgotten the author-name/story-title and only remembered fragments of the plot which was enough for Google to find the play.

Enjoy!
