An old lady handed her bank card to the teller and said “I would like to withdraw $10”. The teller told her “for withdrawals less than $100, please use the ATM.
The old lady wanted to know why... The teller returned her bank card and irritably told her “These are the rules, please leave if there is no further matter. There is a line of customers behind you”.
The old lady remained silent for a few seconds and handed her card back to the teller and said “Please help me withdraw all the money I have.” The teller was astonished when she checked the account balance. She nodded her head, leaned down and respectfully told her “you have $300,000 in your account but the bank doesn’t have that much cash currently. Could you make an appointment and come back again tomorrow?
The old lady then asked how much she could withdraw immediately. The teller told her any amount up to $3000. “Well please let me have $3000 now.” The teller kindly handed $3000 to her in a friendly way and with a smile to her face.
The old lady put $10 in her purse and asked the teller to deposit $2,990 back into her account.

The moral of this story is....
Don’t be difficult with old people, they spent a lifetime learning the skill.
