have an entertainer booked for sunday for ds 5th birthday party. got her no. from a friend who had used her. she works privately not with any agency. ds seems to have chicken pox and covered in spots. whats the siutation - do i have to pay her in full although although we had no contract - or could she let me re-arrange the date. also with the hall i've left £60 deposit and paid £60 for hire - will i lose this as well? thanks
