A former manager of mine (really nice guy, helped me become more professional) met his wife through work when she was just in charge of delivering mail. He's been married for I think 40 years now and at the point of grand kids now.

That has all been denied thanks to HR, because it's too easy to sack men in the workplace just for doing something as simple as asking if they want a drink when you go get one yourself from the lunch room. Work Place relationships often work well because the process of working together usually revels quickly when someone is putting up a front as you as you can compare how they act to how much they actually get done.
