What is the best compliment anyone's ever given you?

Well I didn't know this person at all. But last week at work I am a waitress. An loder lady came in with 2 of her grand kids. And after when they were leaving the grandmother said to me "thank you so much for being so kind and a great waitress." I was really happy to hear someone say this to me. ANd last night at work I had a family of 4 and when they paid the father handed me $10 and I said thank you have a great night he said with the biggest smile "no thank you" It just makes me happy to know that they had a good time when coming in to eat.
