Can breaks be compensated?

I work at a restaurant and during my once a week 6 hour shift, we are allowed a 15 minute break. Then I notice that they deduct this out of our paycheck. I've been reading labor laws and it seems to say that for shifts of 5 or more hours, a 30 minute meal period is required unless waived by both employer and employee. However this restaurant allows us a certain amount of food free, (enough for lunch) and a drink. My question is, am I entitled to compensation for these 15 minute breaks where I'm relieved of all duty and can leave the premises?
