Is it true that if you work in the food buisness as a part-time employee, you do not get paid overtime?

Question Details:

My boss just told me that no matter how many hours you work that you will only get paid for those hours no overtime. So if I work 50 hours a week they will all be at minimum wadge. She said that she could do this because she was in the food business. And food businesses (such as her cafe) have different laws. Important Notice
