How do you handle a client who asks for a "Free Sample" of your work?

[Btaliat]

A freelancer, in any condition, should not work for free. You can however give some discounts, paid trial and some other ways by which you can render to help the clients. Working for free so high level of desperation which is not a good feature of any freelancer, hence, the clients will never rate such a freelancer. What do you think about about this?
