In demolition man shortly after spartan is thawed out he tries to use the toilet after which he declares they have 3 shells where the toilet paper should be.

Later on in the film when spartan finds himself knitting without thinking about it we find out that everyone who was frozen went through a program during there sentence.

So my question is if they could teach prisoners new skills while they were frozen then why would they miss out something so fundemental as using the toilet properly.

My first thought was that the program's were predetermined before the sentence but then I realised that Simon pheonixs program was altered to give his access to the cities computers and a bunch of martial arts skills along with his mission to kill Edgar friendly.
