I think you're misunderstanding. When they were at her home she asked if he wanted to stay at her home or come to work with her. It was at the gate that he realised his mistake. As to why she just didn't refuse to take him... Well, I guess that could be called kidnapping. Obviously I don't know for sure but I would presume she was giving him the option of staying with her or going back, but didn't realise he wouldn't understand that "going to work" with her would mean going back. We'll never know for sure I guess.
