Example of Assumptions
§ A customer at a bank who after cashing a cheque and
turning to leave, returns and says: “Excuse me, I think you
made a mistake.”
§ The cashier responds, “I’m sorry but there’s nothing I can
do. You should have counted it. Once you walk away we
are no longer responsible.”
§ The customer then replies: “Well, okay. Thanks for the extra
$20.”
