  • I want to commend your staff for the excellent job they did for us on Tuesday. They always put their best foot forward in making sure we are satisfied and their service to us is very much appreciated. I use Stax quite often for luncheons... etc., simply because of the quality of food and the service. On Oct. 12th, it was a daylong event. Throughout the day from early morning to late afternoon, your staff made our day complete with food and food service. All of our attendees were pleased with the food and everything went so well. I expressed my appreciation to you staff. To you I say, your employees are to be commended for a job well done.
