Amazingly dishonorable behavior on behalf of some folks who claim to conduct themselves in an honorable manner. Exploiting a programming error is no different than just going in and stealing this stuff from your local b&m. I suspect that many here also would jump the cashier at Walmart is she made a 5 cent error in favor of the store while making your change. I wish that I had seen this while it was ongoing and said something at that time.
