I get really mad if I see someone tipping a nig
Why are you calling people nig, and why do you get mad when you see someone tipping them?
Who TF are you?
It isn't right to call people by demeaning terms, as it is hurtful and offensive. We're all people and should be treated with respect, regardless of our racial backgrounds.
How am I racist, she was black and I got her coffee.
There really isn't any excuse for calling people by racially discriminating names. Have you thought about how this affects them?
