Taking lunches

Does anybody's store give them grief about not taking lunches? I'm a college student so I work at my hometown store during summer and transfer to my college town store during school. My hometown store doesn't care whether or not I take lunches. As far as they care, it's up to me. At my college store, if I go a couple days without taking a lunch my manager will tell me I need to start taking lunches or that it is required to scare me in to taking them. I know it's because of payroll because the GM is obsessed with his bonuses. But as a college student, if I can make an extra $20 or $30 per week from not taking a lunch, I do that, rather than sacrifice that money for my GM's payroll bonus, who makes $130,000+ per year. Just wondering if anyone else has similar experiences.
