Was your COLB a mail order copy? I was under the impression there was no such thing as an internet copy.
Something very fishy about the way dates are applied to a COLB in Hawaii.
The internet copy is something they would use for orders coming through an internet source. The Mail is for one being processed through a snail mail order. Then there is the front counter. Thats what I was told, I have no reason to believe this kind helpful lady was miss-representing anything.
You're confusing having different stations working on these orders with having different machines. You can determine HOW it was stamped, though, whether by machine or by hand, and they may use the hand stamp for front desk orders because of the low volume of requests, as compared to mail-order and Internet requests. However, if the electronic machine is busy, they can go over to another station and use their hand stamp.
But you can't look at the stamps and say, "This one was done by mail-order and this one was done by Internet order."
