Matthews said the man Monday night lunged over the counter and grabbed her cash drawer. Matthews said her "initial response was to hit him. So I hit him."
Matthews said the two were then "tussling, tussling and tussling," so she asked customers and others witnessing the struggle if anyone had something to restrain the man.
KHOU-TV reported somebody offered handcuffs. Another person produced a Taser, as the fight moved outside.
Matthews used both on the man before police arrived and took custody of the suspect.
