There is no free ride anywhere. Its a good thing too because that would in the end lower the value of the commodity. Just because you take an interest in something is no reason for it to be handed out for free. This is great because there are way too many people that stop by for a quick look and fade away. If each one of those people burned a wallet on the way out, AND THEY DO, it would just waste any free coins the people managed to beg off of people.
