Veteran usher here: We never left the offering at the church.
We don’t keep the offering at our church, either. Goes straight to the bank the day it’s collected. Pastor gives people cash, but since the amount he can give without consulting the council is pretty low, he just carries it on his person I think. We have a food bank and other resources, but they aren’t the sort of things someone would steal.
However, our Communion ware was stolen from the church this past January. Maybe we need to invest in some video security cameras. *sigh*
