It drives me nuts too! I wouldn't mind if they would be considerate and pick up early (and not be here the 2nd I open). For myself I hardly ever take time off so I don't inconvenience anyone and usually work even if I am sick and can barely function. It would be nice to get a bit of consideration back. I am always fighting to get people's schedules for summer and Christmas because if I only have 1 or 2 kids I want to either close or go on outings and need to give parents notice. I understand they are paying me but I wonder if they would think differently if we charge per month instead of on a daily rate? I wish people would want to spend more time with their kids too, that makes me sad.
