fines?

[OnePlus69Is70]

I was wondering how other chapters handle fines, or other disciplinary measures. Right now, we don't have anything we can do to brothers who skip chapter meetings or other mandatory events. We don't want to institute a fine, because it wouldn't do any good- some brothers are rich enough that we'd have to set it ridiculously high, and others are so poor that $20 would mean they couldn't eat for a couple days. We want to use something other than money, but we're really at a loss.
