An elderly lady handed her bank card to a bank cashier and said, “I would like to withdraw £10 please".The cashier told her, “For withdrawals less than £100 please use the ATM machine.”The elderly lady wanted to know why.The cashier returned her bank card and irritably told her, “These are the rules. Please leave if there is no other matter. There is a line of customers behind you.”The elderly lady remained silent for a few seconds, then handed the card back to the cashier and said, “I wish to withdraw all the money that I have in my account.”The cashier was astonished when she checked the account balance to see almost £500,000 in the account and said to the lady "the bank doesn't have that much cash currently. Could you make an appointment and come again tomorrow"?The elderly lady then asked how much she could withdraw immediately.The cashier told her up to £3,000."Well, please let me have £3,000 now", she said, and the cashier then handed it, very friendly and respectfully to her.The elderly lady then put £10 in her purse and asked the cashier to deposit £2,990 back into her account.THE MORAL OF THIS TALE;Don't be difficult with elderly people, they've spent a lifetime learning the skills.
