Uncooked rice is what was used here in the North. If there was talking or goofing around in church, we got 45 minutes (the length of time our services were). Only happened once to me and that was because I accidentally dropped the money dish when it was being passed. I think I was about 6 or 7 at the time; I'll never forget watching the kitchen wall clock the whole time (I was supposed to be praying, but of course, ....).
