What if bartenders could make custom drinks the same way tailors make clothing? Except, instead of needing the raw fabrics, they'd just need to be at a bar. People could ask bartenders for common drinks that arent on the menu (vodka on the rocks, etc.) and tenders could come up with special drink mix recipes. And maybe recipes could be saved and re-used similar to how macros work?
This could be fun, now that alcohol can no longer be consumed at people's homes. I know there'd be the issue of which skill to tie it to... so perhaps only people who are employed as bartenders, or have been in the past, could use this feature?
