Bartenders should be able to *twirl containers without spilling the contents.

[Kotlol]

Some kind of juggle like skill where while you're twirling drinks you can pour the contents of everything that is being twirled into things you click

So, you could mass produce drinks by filling out pitchers, juggling them, and clicking glasses to mix them directly into it

Clowns can already juggle containers with liquids in them.... this is no exception. Put it in.
