Where I last worked they used to get mad at me for not taking my lunch breaks. I didn't like being off the clock and I preferred getting paid. Also, I didn't always have a break of customers to naturally break to stop working. Many days I would come in and work 9-4 and wouldn't eat for the first time until I clocked out. I was one of their best when I was there. Being a little hungry isn't the end of the world.
