Staff from a Calgary Plumbing company found a 1 Kg gold bar worth about $50,000 while renovating a bathroom. After inspecting the gold bar, they contacted the home owner to inform him they'd unearthed some treasure. http://calgaryherald.com/news/local...-gold-brick-while-renovating-calgary-bathroom The plumbers say they always return what they find. It's good for business I suppose and the media coverage they got will most obviously reward them with more work. Doing the right thing always has a karmic reward.
