Not her fault. A lot of people make this mistake; a coworker of mine was driving down into the states (from Canada) to run a training course for a company. The customs officials asked him what his business was in the states, and the sentence he replied with happened to contain the word "work."

After ten hours of sitting in a room he was turned back, and we had to fly someone else down to teach the course. Moral: when you're asked why you're visiting a country, do NOT reply with anything that could be (intentionally) misinterpreted as "to find work."

More excited and naive really. Main reason was a holiday, going along to sing in a small pub was only an added bonus, non paid.

That's Stockholm Syndrome talking. You're standing up for evil. Be ashamed, and change your tune. Really.
