Scott went one time with 2 of our canisters...the guy only filled one. Scott pointed out that he didn't fill the other one. The guy started to argue with him about it. The manager came over and asked what the problem was, he told him that he didn't fill it (he watched him only do the one). The manager took it and sure enough not filled!! We would of taken them back to work and had only one filled...so either lazy or trying to pull a fast one....i'm betting on lazy!
