Thankyou all for the comments, very helpful.
I think it's almost as she is paying for the previledge of going to work.
Last week she had 5 clients and if she had to pay for parking and after school club would have been out of pocket.
When I see her tomorrow, I'll show her this post and we will look closely at the paperwork.
She's invested so much ( training, insurance, flyers etc) into this, I really don't want it to fail she wants to be self supporting. She worried about being mobile, as well as seeing people in her rented property as has already had inappropriate requests, believes she will be safer in a shop with other workers.
