How does Pumbkechook treat pip before his visit to Satis House?

Mr. Pumblechook is detached and uncaring. He sends Pip straight to bed in the attic, and in the morning, he feeds him very little. Pip considered Pumblechook to be "wretched company."

I considered Mr. Pumblechook wretched company. Besides being possessed by my sister's idea that a mortifying and penitential character ought to be imparted to my diet,--besides giving me as much crumb as possible in combination with as little butter, and putting such a quantity of warm water into my milk that it would have been more candid to have left the milk out altogether,--his conversation consisted of nothing but arithmetic.
