Ripped off at Recycling Center

My husband went to turn in his cans and bottles at the recycling center in the R&N parking lot in Exeter CA. He always double checks the scales. They emptied the cans into their bags to weight and the scale showed 6.7 lbs. When he went to collect the money the paperwork said 3.4 lbs. He argued with the lady and she of course disagreed so he told her that they cant even go back and reweigh them because she already emptied them. Just beware when you go to a recycling center, ex specially a small one to watch the scales carefully and ask them not to put away your stuff until you've been paid. Avoid the Exeter recycling center in the R&N parking lot as much as possible because they do cheat you out of your money. Money that you just might be depending on for gas or groceries or other bills.
