Expresso is fine on business lots, it doesn't seem to be as beneficial as in the dormitories but it can do the job. I've been using it an awful lot
. If you have others drinking at the same time, the chatting will slow things down and make a cup more beneficial. If you let the energy get too low, the expresso won't be much use. It will only work well up until a certain level. You can use Energisers on business lots by the way, but if you use SnapDragons it seems a waste to use it just for energy.
I like the sound of 'Break takes THEM!' Breaks are just wasted on them right now.
