So I pick up these four scousers, two lads and two lasses from this house where they had been at a party and spent the night.
I tell them some scouse jokes and they laugh, especially at the one about a scouse in the cold. They are all about 18 and dressed in chav, they are talking about 'the car' and if it will still be there. "Never mind" says one of the lads "We can get another" 
So one of the lasses asks how much it will be and I tell her "Well, get the purse out ______" she says to one of the lads and the lad pulls a vast silver granny purse from inside his hoodie. They all watch as he checks the contents. The lad chuckles and smiles at me, I try not to notice anything and not to laugh.
"Even got the tip" he says.
