Today was my day off, but I agreed to look after a child on a one off basis because normal childminder was on holiday. She wanted me to do 8.30 - 6, then the night before said she would be early as work was crazy, which I said was fine. She arrived to pick up her child half an hour early. Then asked me for a refund on the half hour. Did I mention it was my day off? heehee.
