I mean I agree, but at the same time if you work in food service you’re not technically supposed to let your beard grow long, and you should always have your hair (if it’s long) in a ponytail/bun or wear a hat/hairnet.
Still, I agree. I went to a private Christian high school for a couple years, and it was also the same time that I wanted to grow out my hair. I didn’t get told to cut it until like the last few weeks of school, and both me and my mom ignored it. It was my last year at that school anyway.
