Ok, that rant was random (forgive me, I am watching a circle get cut
160 to 260 times) but I want to give my opinion on the matter for
future users of the machine and the dirty-shop.  I want there to be a
consistent message and I want other dirty-users to know that other
people have their back.  We have put a lot of work in to the laser
room to make ventilation a non-issue, but whiney bitches don't know
this.  As far as they are concerned, we're all asshole with no
consideration for other people in the space.  We aren't and they need
to know that.  We also need to know this.  And we also must have the
information needed to express this.
