After shopping a Grandma goes into a cafe to have a coffee and a Mars Bar. The only vacant seat is next to a punk. She is not too happy about sitting next to him, so when she goes to get some sugar she puts her Mars Bar in her bag. When she returns to her seat, the punk is eating her Mars Bar. She is pissed off so she reaches across and takes a bite of his chocolate cake. The punk is shocked that the Grandma would do this. When the Grandma arrives home she finds her Mars Bar in her bag. The punk had been eating his own Mars Bar.
