She wants to know where your attention goes on the job. If you blurt out, "I loved the people I worked with," it would lead her to the idea that you are easy to get along with and a team player.

There is not necessarily a wrong answer here, but there could be a more helpful answer to lead the interviewer in the direction you want them to go. Zero in on the quality you would like to support. In the sample above, being a team player was reinforced. And that's a good one for a salon. If you want to show customer service is important to you maybe say something like, "I enjoyed making people smile when I gave them their morning coffee drink. I feel like I made their day!"
