I think people adding their casino chips in the church plates is great!
Some of those people probably spent most of their money in the casinos and if they go to church and happen to have a few spare $1 chips to throw in, that's great!
Even the idea of someone adding a slot machine slip with credits on it into the church plate is a good idea.
This Chip Monk has the right idea; save all the chips up until there's enough to go cash in at a casino.
Chips = $ as far as I'm concerned, even if it's only a few bucks at a time.
