"The ethanol is a longstanding cultural tradition. You don't have to partake, but hosting a large Vor social gathering without it would be sort of like - I don't know a good Cetagandan example. Ask Miles for one, maybe; he's been to Cetagandan social gatherings. It would be extremely off-putting to the guests. You don't have to dance, either, but again - abstaining for yourself is one thing; denying everyone else the opportunity is another."
