Quote from the link: 

Human behaviour experts have always studied the impact of physical surroundings on human behaviour. They have established that physical locations are some of the most powerful cues to behaviours. As Wendy Wood, professor of psychology and neuroscience at Duke University, puts it, “ Even though people think they’re making choices, many of our repeated behaviours are cued by everyday environments”. Humans are like chameleons who have the ability to change their colours to suit the surroundings. We speak softly in libraries, we are boisterous in stadiums.

Most of our Metro stations are at a physical level that is different from the rest of the surroundings. Metros are either elevated or they are underground. A Metro station invokes a ritual of stepping out of the ordinary world into a “sacred” space. The same level difference (and the accompanying effort) adds to a feeling of exclusivity and spirituality to our places of worship too. "

Kinda strange. And yet true. That our behavior is somehow modified based on where we are. If we wanted to change someone's behavior, place that person constantly in environments where a different behavior is expected. What happens when the person returns to his "home" environment?

Another interesting thing I realized is that each of us creates an environment around us, an aura. We carry ourselves in a particular way. That is what tells people whether we are a cowshed or a metro station. And people treat us accordingly.
