This is from Hemingway's To Have and Not Have. It's not clear to me where they were having lunch.
Out at the house Marie and the girls were having lunch. "Hello Daddy," said the oldest girl. "Here's Daddy."
... (conversation omitted)
when the girls were out of the room he said to Marie, "Cut it up, will you?"
This looks strange to me. At the first sentence, they were all having lunch "out at the house." And after conversation "the girls were out of the room." I wonder where Marie and her girls were having lunch first. May at terrace? Or the yard?
