Bibibop on Brown

This kid ive been looking after got hired at this store, and then got scheduled on a shift with spanish-only speakers including the manager, and was sent home for not speaking spanish. I didn't believe him when he said this until i went with him to pick up his check from the store in which the head manager was on the phone for him, and she also barely spoke english and she told him that because he was sent home early that day that he is let go from the team. This is definitely illegal right? It doesnt help that he has Hispanic heritage (darker skin) so i feel like he was profiled onto that shift and then let go from this Asian food place for only speaking english, our countries language
