If they cancel their standing appointment but want to reschedule for say the next week, do they keep their discount? If they are still within the 3 weeks, or if its something we are planning around like vacations, etc, I am happy to leave it as is. If its a last minute thing, they get charged full price for that one appointment. I always ask them if I can put them back into standing when they return. I don't assume. I'm happy to see them either way.
