It's wrong to cheat the elderly and infirm.
Vera is a cashier at a grocery store and has just finished ringing up Idella who is elderly and frail.
Vera wants to decide how much change to give Idella.
Vera looks at the till which tells her the amount of change and gives Idella the amount shown.
Vera looks at the till which tells her the amount of change, and knowing Idella can't really see it, gives her only half the amount.
Idella is glad that she has a cashier she can trust to help her get through transactions.
Idella later is short on money and runs into some problems when buying her medicine.
