I knew one person who spoke that way, a HS classmate that I, uh, got to know really well. She seemed to be an outlier in that respect, because I never heard anyone else in the area use that ellipsis.
But English is a sloppy language when spoken. For instance, the indicative subordinative conjunction (that, who, etc) is quite frequently dropped. But I suspect other languages tend to drop elements in speech when the omission does not severely impair clarity.
