Does Dolphus Raymond drinks whiskey from a brown paper bag?

To give the town a reason to why he supports African American's. So they can call him a drunk and that's why he acts that way heres the quote

why do I pretend? Well, it's very simple,"..."Some folks don't-like the way I live. Now I could say the hell with 'em, I don't care if they don't like it. I do say I don't care if they don't like it, right enough-but I don't say the hell with 'em, see?" ..."I try to give 'em a reason, you see. It helps folks if they can latch onto a reason. When I come to town, which is seldom, if I weave a little and drink out of this sack, folks can say Dolphus Raymond's in the clutchesof whiskey-that's why he won't change his ways. He can't help himself, that's why he lives the way he does." ..." It ain't honest but it's mighty helpful to folks. Secretly, Miss Finch, I'm not much of a drinker, but you see they could never, never understand that I live like I do because that's the way I want to live.
