I know!
This is one of the worst things.
I was on a date at the Lounge, and Holly Alto came in and started dancing.
So my Sim's date cancels out of the conversation, stands up, and goes to just look at Holly dancing.
My Sim literally couldn't get them to come back and chat, like the date's interaction to "Watch" wouldn't cancel so my Sim could get back to talking.
Since deleting the speakers caused the lot to be labeled as incomplete, I ended up having to wall off any speakers.
Now no one can dance. I'm not happy with this solution, but at least my Sim's date stopped watching Holly dance.
