A little girl, about 4 years old, is out playing in her garden, and is fascinated by the house that's being built in the plot next door. The builders see her watching them, and she's so cute they ask if she'd like to help them. Eagerly she grabs her little toy wheelbarrow and squeezes through a gap in the fence.
The builders are really fond of her, and make her feel really important, pushing a couple of bricks around in her little wheelbarrow, helping to sort nails and screws, that sort of thing. At tea break, they invite her into the port-a-cabin and share their sandwiches with her. This goes on all week, and she's really enjoying being a builder.
On Friday they get their pay packets, and they each fish out a bit of small change, put it into a brown envelope, and give her "wages" to her.
Proudly, she shows her mum. "Look mummy, I've been working all week and I've earned some wages !"
"That's lovely", says her mum, "Will you be working again next week ?"
"Yes", says the little girl. "Well, as long as those useless ****s at Jewsons pull their fingers out of their arses and deliver the ****ing bricks on time".
