1. A person might not trust the site and wants to use the faucet money to test the site features with the sites money and not his/her own money at the start.

(Introduction to the site or a FREE demo) As Dusan replied above, players are able to bet zero amount for testing purpose. Testing the game does not need real balance is good already, faucet can be useful for sites that does not allow zero bet.
2. A person might not have enough money to gamble and needs a kickstarter to get them going. (One of my friends family members started with faucet payouts on a site and he won a jackpot with that, he now has more BTC than the rest of the family)
This kind of story may bring bad effect for the site as it may lead to faucet abuse. The story motivate others to win big from the faucet only with no intentions to play with deposited money.
3. The faucet motivates people to regularly visit the site. (Say you have set aside $100 for gambling every week and you gambled the whole $100 in the first 3 days, then you still have a motivation to visit the site to claim the faucet. This is good for the site, because it increase the activity, even if the person just hang around the chat section.
There is now reload and rakeback as well as much more other better promotion/giveaway compared to faucet. So real gamblers who have spent some money on the site will come back for that things instead of the faucet. There is also chat rain on the site, people can still hang around for that reason.
All in all, faucet is not really good thing anymore at Stake as there are many other better offers.
