Am I missing something?

I started a new job at a restaurant and my trainer hates me. He talks shit around me when I'm right beside him but he doesn't know that i speak Spanish too. It was only my second day today and he's bitching and complaining about how i don't know things. But that's the part that puzzles me, he's supposed to be training me and I'm inexperienced. He also hates it when i do my job right and give it my all. I've caught him cutting corners these past two days and when i call him out on it, he tells me not to worry about it. Today I really pissed him off because i tried extra hard and mopped the floors all good. I know it ain't fun but the job has to get done properly. I take great pride in my work, even if it's as simple as mopping floors. Should i talk some sense into him?
