An old lady with a shopping trolley packed to the gunnels is waiting patiently in the checkout queue.  To pass the time she engaged the man behind her in conversation. 

'Please could you help me load my groceries on to the belt?'  She asks him.  The young man was pleased to assist the woman.  'May ask what's your name' she said'.  He told her was called Brett.

Then the old lady cracked up and began crying.  'Not only are you the spitting image of my son who was killed in Iraq', she blubbered, 'But also you are called Brett - the same as him.'   Eventually the little old lady pulled herself together, and between the two of them, they put all her items on the belt and through the checkout.  She mumbled something to the check-out assistant, and shuffled off out of the store and into the sunset.

Brett was in a bit of a daze; more so after he put his half dozen items through the checkout, only to be confronted with a bill for $257.82.  When Brett queried the total with the assistant, she said that his mother whispered that he would be only too happy to pay for her groceries as well.
