Nobody listened.
I find myself with a case of both sider-ism on this. One the one hand (the hand that really should win out), we should all be able to act as decent empathetic people with the instruction following capabilities of a 7 year old when the situation dictates. But on the other hand, when you treat (and pack) your customers like a bunch of damn cattle, don't be surprised when they act like a bunch of damn cattle.
