The Car Boot Sale
He comes across a stall selling books and after a bit of rummaging around finds a title called "Zen Buddhism"
"How much for this book?"asks the man
"1 pound"replies the vendor
"OK I'll take it"says the man and then he hands the vendor a 5 pound note.
The vendor put the fiver in his pocket then went to serve another customer. 5 minutes passed and the man says to the vendor"What about my change mate?"
There was a slight pause then the vendor spoke. "Change must come from within"the vendor replied
