Okay, so I have been lurking. I have a reasonable understanding now of how the pricing works and have had modest success grabbing pennies ( several newtones, and some compressors). For the first time today I was actually had my transaction stopped in a most dramatic fashion. This was partly my fault. I shouldn't have tried to get another nutone penny while I was buying a few normal items. I was caught completely off guard when they penny rang up and the SCO began shouting at me like a crazy person about not being able to sell the item. I attempted to continue the transaction the SCO snatched the item and began swatting at my terminal to cancel the sale while I was paying. The sco had little success but then began madly swatting at the main terminal wailing about not being able to sell it for a penny and something must be wrong. SCO managed to cancel my whole transaction, and called the head cashier over who offered to sell it at last clearance. I probably should have taken it but instead I made a quip about just buying one off ebay. I was rather pissy about some psycho going off on me while I was checking out. Any suggestions as to how to handle this now / in the future. The main idea being that I want to keep harvesting pennies as they show up but not draw undue attention to myself as clearly happened here. I will be avoiding times when this crazy person is at the sco that is certain. Any wisdom to be shared?
