Customers hate waiting, but they also hate to be hounded by sales associates. Many customers feel uncomfortable asking for help and will leave if they don’t quickly find what they need. Or they just look up the item online and order it instead.
Example Use Cases:
"Been waiting for 20 minutes. I'm leaving."
better employee utilization
"Can't find my size. Can't find a sales person either."
"Does my coupon apply to this item?"
