I have mindee 1 for 3 days a week. The days used to change from week to week but now that I have more mindees everyone has to stick to their days a bit more. This week mindee 1 was supposed to come for an extra day today but got a text at 11pm (after I'd gone to sleep) last night to say that he'd be coming for half a day instead. Would you charge for a whole day or just the hours that mindee was here (approx 4 hours)?
