He doesn't trust anyone.

He's been on the streets his whole life. Starving, while all the pampered nobles made fun of him and threw food away in front of his starving self- he was only a child. As an adult, he's now able to secure a very poor paying job, where he slaves away for the people he hates most- the nobles. Even though he hates it, he's willing to give up his dignity to eat.

Right now, he's serving you, another noble, in your shopping around the expensive clothes store.
