I am a freelancer and have been doing writing/research and now genealogy for about 15 years. I would actually do Who Do You Think You Are for free - that's a huge show with 6 million viewers. It's about getting your name out there.
But I have also been approached to write blogs/articles for various websites and when you look into the website it's something you've never heard of, or in a very narrow niche or just really poorly put together. It's clear that they are an amateur outfit who haven't a clue.
The irony is that the celebs who COULD generate a huge amount of publicity for a baker, florist or similar will pay for their services. You never heard of Elton John trying to grift a freebie cake for his kids or Madonna or Tom Cruise after someone to paint their portrait free of charge. Even though the events hosted by the real A-list celebs are featured on the pages of glossy magazines across the globe.
This woman's protests that she didn't know do not wash. Of COURSE she knew. No party planner is going to go off and start organising a party without getting a full brief and budget from their client. She is rude, grabby and just a bit thick. Well done the baker.
