What are unreasonable expectations?
Unrealistic expectations are rigid. They don't leave room for changing circumstances or allow us or others to be flexible. Sometimes the expectations might seem reasonable, fair, and realistic, but your experience reveals they can't be met. Your expectations can also create more problems than they solve.
How do you manage unrealistic customer expectations?
If your customer's demands have become unrealistic or impossible, try to remain calm and professional. Get to the root of their problem by listening actively and empathizing with them. Explain your own position clearly.
