i had taken in a load of personal scrap iron which I had taken into the Sacramento location at130 N 12th street the had quoted me a price and told me the price would be good only on loads over 1 ton I had weighed my truck on our own certified scale with a tare weight of 4540 and a gross weight of 7160. When I weghed in at Sims I had a gross of 6720 and a tare of 4640.I pulled off the scale on check out got back in line for a reweigh and they had held up a truck to buy time and get personel from the front office into the scale house...when I had confronted them about the 540 pound difference I got the run around and the our scales are certified mumbo jumbo....there caught and knew it
