reminds me of a story my grandfather told me: he worked at a shipyard, they had a foundry, and a lot of used casting sand that workers could take home for fill or whatever, if they needed sand. So his friend would leave the gates with a wheelbarrow of sand every once in a while, and the guards really thought he was up to something as he would always smile big at them, and they would poke the sand to see if he was stealing tools or whatever, hiding them in the sand. He was stealing wheelbarrows.
