I guess I was looking at it more from the perspective of a new customer. The mind plays tricks on us humans - we can look at a packet or bottle of something, know exactly how many items are in the packet, but if it looks more empty than full, we can (falsely) believe we are being short changed.
You and I will keep buying it, but a first time customer might not go back for a second bottle - which we really want them to do.
