In Georgia, USA I hear sentences like "get some milk out the refrigerator". I have always heard "get some milk out OF the refrigerator". Which grammer is correct?

(I reposted this question so I would not be anonymous)
Standard English is 'out of'.

I am still wondering if dropping the word 'of' is also correct.
Students: We have free audio pronunciation exercises.
(the mispelling of the word, 'grammar', was just a typo)
It's correct in the dialect they're speaking, but not in standard English. Generally speaking, mature native speakers of a language don't make mistakes (unless they themselves identify them as mistakes, like accidental misstatements). Any differences between their usage and standard usage is attributable to dialectical differences.
CSnyder can you answer my question?
Students: Are you brave enough to let our tutors analyse your pronunciation?
Thanks! I didn't think it was correct standard English.
There are some collocations where it sounds OK to omit 'of', eg 'Tom went out the door'.

But in a context like yours, I would say it sounds archaic or close to archaic.
