in the most basic form, the storehouse holds everything the bishop's ward has donated. he holds on to it until a family in the ward is in need or when there is a natural disaster and many families are affected.
You're thinking of something else...those do exist, but the Bishop's Storehouses are different.
The Bishop's(or Lord's) Storehouses are stores with food, clothes, and other basic amenities. They are all provided by volunteer LDS farmers, local storeowners, etc., and the Storehouses themselves are staffed by volunteer LDS Church members. Items at the Bishop's Storehouses are sold for very low prices to families that cannot afford things at regular grocery stores. You do not have to be LDS to shop at a Bishop's Storehouse, but there is a maximum salary for people to shop there(I'm not sure what it is).
I've heard wierder ones. the people in my ward are so off that one of our members calls it the "jerry springer ward". one lady went crazy and started spewing a bunch of bible verses. I actually thought she was going to pull out a crucifix and say "by Jesus christ, I rebuke you".
Lol.
Sounds pretty nice though - people talking about their mission and that.
Well, it's not just that. Often, people quote things from the Bible/Book of Mormon or tell parables/fables, etc.
