These they will
never implement simply because in a lot of countries there are restrictions on depictions of alcohol and smoking use in media, especially games, and if SE did implement it, it would result in the game having to bre reclassified as more mature, which restricts a lot of potential players (and thus impacts the game's profits), something SE simply will not abide.
That is, after all, a reason why
these tropes exist. (Note that this is not the place to argue how stupid or inane such censorship is or not - if anyone disagrees with it, petition the relevant governments to change it, please don't argue it here as SE is only naturally complying with law).
Anyway, getting back onto topic, the emote I'm really waiting for is a proper /curtsey emote - my character was raised in high society and is a knight: curtesying would be practically demanded of her (the standard /bow emote does not suit her sadly).
