Why is it any business of yours what the mom does after hours - just because the kid was a brat at daycare doesn't mean mom and daughter etc have to suffer and why should mom have to deal with temper tantrum by refusing child dessert. The other side of the coin is parent shows up at the door and says child misbehaved before coming and therefore dont' let him go outside to play today or don't let him go on the museum trip or don't let him go in the splash pad - are you really going to cancel the promised plans for everyone else and stay home or deal with a tantruming child on your outing when the "problem" was between the child and parent.
