I’m working on a Business exercise and need support.

Buying a New Pair of Shoes

You buy a new pair of shoes on  sale. The printed receipt states very clearly that the shoes are not  returnable. After you get them home, you wear the shoes around the house  for a day and decide that they just don’t fit you correctly. So you  take the shoes back to the store. You start to yell angrily about the  store’s poor quality service so that people in the store start to stare.  The clerk calls the store manager; after some discussion, the managers  agree to give your money back. Is this ethical? Provide an explanation and justification for your decision to return the shoes, and why your tactic was necessary.
