Our own donation bucket is mostly to raise funds for "starving artists" so they can have free space in the gallery, and we can afford to advertise their work. We've been doing the collecting informally so far, but now I'm inclined to look into one of those donation boxes you can BOLT to the table or floor, made with bulletproof plexiglass. But that brings up the whole "spending $200 for a collection box that collects $200 a year" issue... is it really worth it?

For now, I guess we'll just be more vigilant.
