Who says he didn't have one? He had to have some source of income to buy a trailer and a television and booze (all which we know he owned thanks to the opening cutscenes).
he just takes what he wants, like that club entrance.... Barman: sir, you have to pay..... Donte: F**** YOU! *hits in da face* Store manager: This Tv set isn't free of charge! Donte: F***** you *hits clerk's head on the counter* Car seller: Sir, you canT take keys to this trailer.... Donte: F***** YOU *overrides seller with a trailer* Dante's face: http://collider.com/wp-content/uploads/beavis_and_butthead.jpg I love free of charge service.
