How we cite our quotes: (Part.Chapter.Paragraph)
Quote #1
With that flourish, and seeming to have talked himself rather more drunk and much more ferocious than he had begun by being, Mr. Riderhood took up his pint pot and swaggered off to the taproom. (2.6.43)
It's no secret that alcohol can make a person chatty. In Riderhood's case, this means he talks more often and more loudly. This is all pretty consistent with his character, really, since the guy isn't known for his restraint or self-discipline.
Quote #2
The honest man who gained his living by the sweat of his brow remained in a state akin to stupefaction, until the footless glass and the unfinished bottle conveyed themselves into his mind. (9.12.165)
Riderhood is so used to having alcohol that his brain only snaps into action after he gives himself something to drink. Now that's what you call a chemical dependence.
Quote #3
This had a modest self-denying appearance; but it soon turned out that as, by reason of the impossibility of standing the glass upright while there was anything in it, it required to be emptied as soon as filled. (9.12.52)
Riderhood has a clever trick whenever he splits a bottle of booze with someone else. He specifically uses a type of glass that has no feet, meaning he can't set it on a table. This means that whenever someone fills his glass, he tends to empty it almost immediately and gets more of the bottle in the process.
