I cashed in a small load a couple months ago...alum cans, #2 copper, couple batteries, couple brake rotors. When I got my check I almost dropped a load...it looked waaay to small. Upon ticket inspection the guy at the scale put my copper as #2 insulated...I asked him about it, he looked at it, apologized, cut me a new slip and told me if the cashier had a question to call him and he'd verify his mistake. They simply voided my check and cut me a new one.
