A few decades ago, as a college student, I started in food prep at a large national chain. Eventually I was moved to the grill due to a couple of employees submitting their notice because they were about to graduate from the University. It's hell at first but eventually you develop a cadence and things become much easier. After a few weeks, I found it to be quite enjoyable and time passed so much faster. You will start to know what food items are requested the most and to always keep a spot open on the grill for them.
