My boss tried to talk my 15 year old co-worker out of his break, I convinced him to take it

My young co-worker asked out supervisor today “should I take my break now or wait until later” My boss responded saying “It's an optional 15 minute break, you're kind of a bitch for wanting it at all” and he walked away… I told my co-worker to go take his break, because it's the only company benefit he gets. We don't have insurance, PTO, nothing..so I wasn't about to let my boss bully him out of his 15 minute break. He realized I was right and happily took his break. A 35 year old bullying a 15 year old out of a 15 minute break is just so shitty
