When Giovanni said he'd order dinner for everyone. He meant DINNER FOR EVERYONE—with all caps for emphasis.
Angela didn't expect to have so many foods arrive at her apartment—it was like a feast for the entire neighborhood—though she could be exaggerating.
She had a similar reaction earlier that day when Gael ordered eight boxes of pizza. There were eight of them in her place—her, Gael, and six of his men. They had one box each because apparently, you don't share pizza in Italy. She didn't finish hers, but the men ate their pizza without problems.
So when dinner came, and Giovanni's orders arrived, the counters were filled with food. They were all delicious dishes, but she was still surprised to see that he ordered that many. Would they be able to finish them all?
