Lazy waiters, a kitchen stove with worrying sanitary conditions, and sexual jokes about each other's faces without hearts jumping, "Hello Serving" gives us a unique taste of the behind-the-scenes taste of the catering industry. As a director and screenwriter, Rob McKelick has a considerable say in everything in the film. The experience of working in a similar barbecue restaurant in Orlando for several years has made Rob have a lot of subtle psychological experience for waiters and customers. The situation is the same as that of the lost Dean in the film, but Rob took a part-time study in the university, determined to change his future destiny, and the ups and downs of being a waiter were written into the script by him.

Rob admits that his idol is kevin smith, a legendary figure in the American independent film industry. In 1994, Kevin scraped together $27,111 to shoot the hilarious comedy Crazy Shop Assistant in a convenience store where he worked for five years with 16mm black-and-white film. Rob is determined to keep up with Kevin and expect to put Hello Serve on the screen with a lower budget. He took advantage of his work to get to know a local producer at the dinner table and got about $21,111 in funding. Just as Rob was gearing up for the opening of the film, there was good news from Hollywood. Universal Picture was interested in investing in filming. The script changed hands among many companies several times, which lasted for seven years. Finally, Lionsgate's investment made "Hello, Serve" finally come out.
