Sometimes customers think they know what they want until you give it to them. In this example, the landscaper followed instructions, but the customer changed her mind. Instead of getting frustrated, the best way to respond is to ask questions and find out exactly what you need to do in order to please the customer. There is no need to take things personally. Simply listen and humbly respond. If you have ever received criticism from a co-worker or boss, talk about how you listened and responded by taking action without letting your emotions get in the way.
"I was almost finished with a project, and I asked the client for their opinion. She told me she didn't want the roses to be near the walkway but preferred I put them by the fence in the front of the yard. She also didn't like the color scheme of the flowers. Even though it was difficult to make these changes at the last minute, I knew exactly what I needed to do. I asked her about the specifics of the flowers she wanted instead of the petunias and begonias. She was able to tell me exactly what she wanted. In the end, she was very happy and she even referred me to one of her friends!"
