God it must be great to have so much time to fully clean a room after each client. When I'm booked back to back I only just have time to change couch roll etc before sending my next client in. Anyway back to the question asked, my boss has me do up my own hours at the end of the week. So I fill in a column of all the days with my start time and end time. If my last client left at 6 and I was there til 6:30 I put 6:30 on the sheet. She doesn't expect me to hang around cleaning up or waiting on her last client to leave for free. If its only 10 minutes I don't bother putting it down but that's just my personal choice.
