"You can't be a politician then"

Classic moment at the newsagents this morning. I had to get the whole pile of papers - part of the job, and given that is £15 out my nil wage packet this month I asked for a till reciept.

Newsagent, peering over the great stack of virgin forest on the counter;
"Do you want anything else on that," as he typed in the amounts.
"Nah, that'l do, can I have a reciept?" says me.
"OK, here you go".
I then picked up a compulsory, Lord it's Sunday morning and I have to go to work, can of fizzy pop and dropped it on the counter.
He typed in the price and laughed as he took my money,
"Well, you can't be a politician then!"
