Customer service. Scenario 5 of 6. Correcting a colleague
That is not right
You are on the shop floor next to Reece, who has worked here longer than you. You hear him tell a customer that a laptop comes with a three-year warranty. You know it is one year. The customer is about to buy it.
The principle
If a customer is about to act on wrong information, correct it before they do. Offer to check instead of contradicting, so the facts get fixed and your colleague keeps their dignity.
