We prefer it be from your own stockpile.
Not only does the gym stay down longer when you rely on admins, since we aren't online 24/7, so it's down waiting for us...
But we don't like being gym leaders bitches, knowing that it could have been done with your own materials.
"Can I get a stack of cobble for my gym"
r. u. srs.
tl;dr?
Do your best with your own, ask us for special needs.
Especially when those needs are NOT a needed remodel, and simply you wanting a harder/more interesting gym.
