Thanks for making this mod. It has been fun to play with!

It seems like there may be some parts of the files that are broken:
1. The restaurant makes sales, but no workers ever show up to work.
2. The layers may be out of whack. the people passing by walk behind the counter. If I'm reading the documentation correctly, the coffee counter should be at the "worker" layer instead of the "foreground" or "walker" layer.

I'd be happy to take a stab at updating this for you.
