Walking into a closing shift where 3 stylists have called out means a lot of work on the backend when customers who don't check their email come in looking for their appointment to be filled and no one's here. Having cancelled appointments made easily accessible to see where they've been rescheduled to / the names of cancelled people would make tracking down individuals much easier. As nice as looking up by phone number is, it would be more efficient to see the cancelled appointment around the time the customer was expecting to arrive.
