Minecraft medieval village, low class rules?

I'm a builder for my friends server, and she have asked me to make a HUGE village with high/middle/low class areas. I've finally finished the low class area, but I'm missing, obviously, the rules, I don't have that much. This is what I have. "Low class shall not enter middle/high class area, unless allowed. Are not permitted to eat high class foods. Any who are caught doing a crime toward a superior, shall be punished be said superior." And that's all I have, but I need more. Any ideas guys?
(PS: If you want, you can make the high/middle class rules too. It saves me points | 3) [Not sure if this helps, but I'm using the Egyptian class system, anyone in the scribes section is in middle class]

Perhaps 'Those of the lower class are forbidden to Enter the Middle/high class districts, the punishment will be severe, and may lead to jail'? (but worded slightly better)
And for the Middle Class: 'All Middle-Class residents are permitted entry into the High Class districts up to 7pm.'

And I think the High class shouldn't have rules, you know, being beasts and all. Maybe a jokey rule like 'High class who even dare enter the filth lower class are forever banned from returning' :3
