Dude.
Why are you being obtuse.
Zoro is the one of the crew that is constantly stealing Sake, and fighting with Sanji over drinking it all. Always drinking.
Sanji drinks wine and other things. Oda has literally made it a point for Sanji to call Zoro's taste in alcohol uncultured at times.
Yet Gaban is the one with a sake bottle in hand fighting drunk, brutish, with axes.
What is wrong with them sharing traits?
