Here's my letter to Chili's via their website:
I stopped by Chili's tonight for a dinner with my friends. We were taken care of by Thomas H. (I believe the first name was Thomas). This has been my best Chili's experience far and away. His brother taught me high school math, so I knew who he was. He noticed my MSU Spartans shirt, and we chatted about Michigan and his brother. After placing our order, he brought us chips "just because". It's small things like that that make me want to come back to restaurants. The food was pretty good, but the check really surprised me. He made my friend's salad a side salad on my course and even took off our drinks. He also made sure to stop by several times and refill drinks and ask how our food was. Wow, what an awesome guy. Needless to say, he got a pretty big tip from me.
This experience alone has made me want to frequent Chili's. It's people like Thomas that help a business thrive. Far and away the best service I've ever had.
