Answer: spontaneity
Explanation:
From the question, we are informed that when Lia entered Nordstrom store, she asked a sales associate named Sarah for assistance finding a pair of jeans, a pair of shorts, a skirt, and matching tops.
We are further told that Sarah enthusiastically agreed to help and treated Lia like royalty throughout her two-hour shopping trip and that Sarah stayed with Lia the entire time she was in Nordstrom's and showed her a number of different styles of jeans, shorts, skirts, and tops. After the sale, Sarah thanked Lia for her purchases.
Lia's experience at Nordstrom's is an example of spontaneity. It should be noted that spontaneity has to do with unsolicited, unprompted and unplanned attitude qnd action by an employee. This was what Sarah showed.
