I’d say the trick animations after your Sims orders a drink are a way of the game “showing” how the drink is made? (It would also depend on the Mixology skill of the service Sim in question.)
Drinks that are not cocktails (thus require no preparation), like nectars and beers, tend to be easier to order, but I’d say you’re onto something: after ordering a drink there’s a significant delay sometimes, specially if townies have been ordering too or if the mixologist is engaged in conversation with a large group.
My report, though, is more focused on the fact that it’s impossible to even order drinks — the mixologist is actively engaged with the bar (hence the trick animations), but clicking the bar doesn’t show any Order Drink/Food… options. As if there’s no one tending.
HALirious9k I’d say in this instance it’s different from making the drink - because it can continue for sim hours without any drinks being served, and involves building bottle towers and breathing fire rather than putting anything into a glass, and the “wait for drink” action doesn’t appear in my sim’s queue until much later, if ever. But yes, sometimes I do at least have the option to order while other times I don’t. It’s just in my experience that when I don’t, they oddly seem to finish up their tricks & chatting sooner, and when the order option finally does appear, they then serve it normally. But just like trying to decide if it’s actually more of an issue on my PS4 than on my laptop, the differences could be meaningful or could just be random variation. It does seem very similar to me.
