John asks Fred if he'd like him to bring some cigarettes back from his holidays for him.
"Yes please -I'll pay you of course!" Fred says.
When John gets back he gives the carton to Fred.
"How much do I owe you John?"
"They were £58!" said Fred
"What?!" says John "£58 quid. I could have bought them in the supermarket for less. Where did you go?"
