What is the compliment that you have been paid that you are most proud of? who gave you the compliment?

It's the compliment that made by a customer where i work as a waiter.

She said that i was relly efficient in serving her and her family as a customer. I felt really proud when i was hearing it because efficiency and customers' satisfaction is all i aim when i'm doing my job, and to know that it's noticed is a great reward on itself
