Sex while dining out

[2dk2c.2]

I made a restaurant and used some of the newer "Dining out" furniture.

The dining booth-set comes with its own table.

But Sims use the table like a chair, and for some reason sex isn't reserved to one couple.

In the picture I have uploaded, two couples are having sex and another sim is waiting for their food.

 

If I knew which sex-acts they were performing I could blacklist the acts, but anyway this is more of a 

"has this ever happened to you?" post,

and there are no errors to report, only the lack of respect for the table (or a bar)

NSFW alert, adult content follows, abandon all (etc)

It seems to have something to do with restaurant items, or one of my mods isn't right, but couches and chairs seem to work fine.

It's those diner-booths that seem wrong somehow.

They function perfectly in a restaurant, they just seem very misaligned for sex.
