The game gives us small tables and benches, please add a smaller serving table too. (without getting rid of the original)

It makes sense, the canteen has no minimum size, and we already have smaller tables and benches.

There are some times where you want just a very small number of residents to use a canteen area. For example I have only three padded cells located in my healthcare department. It'd be nice to be able to make a tiny canteen in that area.

Or, small on-wing staffrooms would be cool to be able to make a suitable sized canteen for the small amounts of staff using that room.
