You've met Mac and his many personalities already, so all I'll say is to be careful; they bite. And fire artillery at you, too.
I'mma Grumpy, resident CBox lunatic, drunken Scottish individual and timewaster. Need anything, I'm probably not the best person to ask, but the staff are good at helping out.
Enjoy your stay, and please don't feed the goddamn Paorou; he bites.
