Here’s What to Say When a Customer Tries to Negotiate or Make Unreasonable Demands

“I wish we could do that …”

When to use it: With a customer who is trying to negotiate a better price or one who is asking for an unreasonable allowance for an error.

Why? Instead of creating an adversarial scenario, these words actually compliment a customer for his intelligence. Do they always work? No. But they work frequently enough to remember.
