A man walks into a minimart whilst whistling quite melodically.
He picks up a copy of the Woman's Own magazine, a Bottle of Gin and a Cadburys Flake.
He then walks up to the counter and gives them to the man behind the counter who scans them in and says:
"Sixteen pound forty nine pence please"
The man who is still whistling gives the exact money to the man behind the counter and then puts the items into his bag and continues to whistle as he leaves the minimart.
A man who had watched the transaction says:
"That was strange"
The shop keeper replies
"He's a regular, that stuff will be for his mother"
