I had also heard of a different banking story. A woman went to cash her check and the teller cashed it. The woman was walking away, counting her cash. The woman returned to the teller and stated "you seem to have maken a mistake when you cashed my check." The teller immediately scolded the woman for walking away BEFORE counting her money, and told the woman in no uncertain terms that "the money is just as it is, since you walked away BEFORE counting it, I cannot change anything now." Kind of perplexed the woman told the teller "that's OK, you gave me $40 too much," and proceeded to then leave! Perhaps we should sometimes THINK BEFORE SPEAKING!
