Just out of curiosity really.. I make cakes as a hobby, they are buttercream decorated rather than fondant and I have made some recently for a few local people (NHS workers and stuff). Someone local asked me if I would make them a cake, I do not know this person but it was someone who knew someone type of scenario.
I sent this message:
"I don't actually have a cake business but I do make cakes for family and friends. I have been asked recently to do a few for people - the ingredients, box and board come to about £9 and I am starting to ask for a small amount (say £10) to cover a bit of my time. I only do swirly icing types ones and I could do you pink swirly one, I will send a picture of the type of thing I mean"
Reading that, how much would you have given me for the cake when you came and picked it up?
