Answer:
Kayla is using a merchandising approach
Step-by-step explanation:
On a normal day, Kayla should have just stopped after telling the customer "The ProSpin GX2 blender is currently on backorder", however, she decided to go the extra mile to assure the customer that despite the out of stock issue, they will still have the product before the end of the week and she can check back at the store instead of gong elsewhere.
