You seem to have issues with the part of the sign that said "but please be considerate".
Adding that phrase to the sign seems to have made you think that anyone that helped herself to the candy was doing something wrong.
No, anyone who went beyond what most people would agree is considerate. Clearly you believe taking it all is considerate and i think that is greedy and detestable.
And even then you seem to be having a lot of problem identifying just why you think what she did was wrong, and wave it all under a cloud of ambiguity called being considerate.
What part of greed keeps escaping you. Cant read?
Greed is NOT considerate. As hard as you are defending that greedy woman, im guessing you dropped a few entire bowls in your bag too in your lifetime. Maybe you teach its ok to your kids too, who knows.
