I am a childminder. I charged a parent for an hour of extra care and she is not a happy bunny. She is happy that I pick her child up from her house and drive the child back for free. She is happy that she signed a contract for two days a week and is getting Granny to do the second day. I am less happy that I retained a place due to our contract but didn't get the gig. But, the fact that I have asked for £4 is just outrageous. Am I unreasonable?
