Maybe is possible to have separated items for males and females? I remember another hack somewhere known as "pee-anywhere", but it was an invisible object and you cannot place it under shrubs. It seems to me that the female animation on shrubs is not so realistic, so maybe your hack would be better for males only.
A little notice: For the european metric based systems (e.g. Windows with Italian, German, French and so on settings), you have to write commas instead points into the decimal values, or you will have very strange results.
For example if you put a value of 1.01 SimPE translates it as 101 and you will have a kilometric height of the sim. LOL
So you have to use 1,01 and so on.
I wrote so because it's seems not enough underscored into the main post and it's a very big trouble if not recognized.
Sorry to say that, because this could be a great hack.
Using your hack (both files installed, the old one manager deleted), I had big troubles. No more ability, for all my employees, to: 1. Establish uniform. 2. Modify charge. 3. Pause his job. 4. Send home employee. 5. Fire employee.
Little Note: I was able to hire non-family sims (in the shop as customers) only if best friends with owner. Otherwise they refuse always to be hired.
Then I removed your hacks, and all works fine as before (of course without the option to hire family member or friends).
