Some of the restaurants such as Red Lobster and Olive Garden have added a survey website on your receipt where you can go there to express your thoughts about the service. My sister and I used to make a road trip into the "BIG CITY" once a month and always finish it off at Red Lobster. We would try to get a table with our favorite waiter when we could as he always made us feel at home. We in turn would post a good review online concerning the service we received from him. Before he became our favorite waiter though, our reviews were good. Our next visit we couldn't get seated in his area but he made a point of coming over to us and thanking us for the kind words so yes, they do see what we put out there. It really made a nice finish for our trip to the "BIG CITY" that day........:-)
