"I just wanted to send you a quick note letting you know what a great job your team did yesterday."
"I was very impressed with Chris' overall service. He did a wonderful job! He had to climb up and down 3 flights of stairs but didn't complain one bit. He is a really, really nice kid and very well-mannered. You are lucky to have such a well rounded younger man working for you."
"Your driver was just a doll. I just wanted to pinch his cheeks!"
