It’s really easy to say it cannot be done. Delivering that line moves the monkey from your back to the other side.
You may think is solves your problem but it only delivers frustration to the other side that is depending on you for a solution. Let me give you a few scenarios:
A customer asking for an exchange because he discovered some clumped up capsules in his bottle of supplement. Sorry, it can’t be done.
A customer asking for a replacement seat because he missed his flight – not due to his lateness but because he didn’t hear the flight boarding call in the midst of the chaotic boarding system. Sorry, we announced it.
Every situation has a best possible solution.
What can I do?
