Employees had to bring a lump of coal to heat the room they worked in.

Maybe require 10 squares per employee?

If anyone knocks on my front door begging for a roll, I would give it to them!

Unless I am in your situation, but I am watching my use much more closely, which is annoying in and of itself?

My brother was in the process of selling his summer cottage and was removing the last of his belongings. It was just getting dark and he was facing a two hour drive home. As he was passing through a northern town he found a supermarket still open, though due to close in 5 minutes. Guess what-that is when they restock and the workers were opening a complete skid of toilet paper for the next day. On reflection it seems obvious but depending on the market it may be better to shop 5 minutes before they close than with the crowd waiting for the morning opening. Happy hunting!
