since no admin has voiced over this, I don't know what's "too much"
I was asked to pay 5 mil and drop 500 of my gold ore once.
Comes to big number, but hey. Keep it in rp, if their demand makes sense and they roleplay - see what can you do to avoid it all.
3 million isn't much.
if they are blunt and keep insisting with no response to your roleplay, eh.. they dont deserve it;)
