when followers leave offerings at a temple, what happens to the offerings?Depends. Coin is spent by the clergy, food is eaten by clergy and/or shared with the needy, valuables are used, bartered, or sold by clergy

Note that usually the disposal results in gain used by clergy for works of the faith (few fat, corrupt, exploiting priests; gods DO watch)
