There's an old film, where there's an older male conductor and a young girl on a train. The girl has entered the train without a ticket and the conductor has caught her. The girl begs to be able stay onboard and offers to work for her ticket. She says she'll do anything. Then the conductor says, "Well, ye gad", and offers the girl a post in the canteen. Now what does this phrase mean and how else would you say it?
