My dad works w/ about 95 % Mexicans and he said for the most part they stick to themselves, but he told me this story just the other day that they were all at lunch and one dude asked him a question and when he turned to answer him... another dude was like, "What the fuck you lookin' at? Don't look at me." And I guess this same guy keeps tryin' to start shit w/ him day after day now, pointing at him like a child and talkin' shit in spanish so he can't understand him.
The situation my dad is in right now, he can't quit his job, he's got a case pending in court and its been coming up in background checks. Until he gets it dropped or is charged, he's stuck w/ this fuck face of a douch. It's pretty sad when ya gotta eat your lunch out in your car to avoid confrontation w/ someone who just wont give the fuck up and starts shit for no reason.
I told him to go to HR, but he said the HR lady is bestest friends w/ the manager of the joint and the douch that keeps fuckin' w/ him is pretty much the managers bitch, meaning they tight and so even if my dad did say anything, nothin' would get resolved and would prolly only make things wrose. And if he can't get his case thrown out in court (which he has very good chance of doing) he will be charged as a felon and will really be fucked job-wise and stuck w/ that fuck head.
