it seems that every one has a bit different approach to hours etc. we currently are open 6 am to midnight as a hybrid. we have cleaners show up at 7am and they clean store and process WDF order till noon. then we have a another cleaner come in about 4-5pm and do a light cleaning. sweep change trash bags etc. most issues are easy to take care of over the phone since we have ability to start and put machines out of order remotely. hopefully this helps some with your questions but local factors may play into your operation such as the if it is high crime etc.
