---Programmer and his wife---

[wife]: "Darling , could you please go to the supermarket and buy a bread? We don't have a bread anymore"
[man (programmer)]: "Allright, i will take a walk to the supermarket."
[wife]: " Ohhh, before i forget: If they have eggs, bring 6 of them"
Back home:
[wife]: "But darling, why did you bring 6 breads?"
man: "They did have eggs..."

This is how the programmer thinks:

<?php
$aldi = new SuperMarket();
$basket = new Basket($aldi);

if ($aldi->hasEggs())
{
    for ($i = 0; $i < 6; $i++)
    {
        $basket->add(new Bread());
    }
}
?>

Result: 6 breads

Who made a mistake? The programmer or his wife?

Classic logistician joke.

Basket::add() needs to be refactored to include an optional quantity parameter. C++ prototype: bool Basket::add(item_t Item, int quantity = 1);. The hasEggs method seems special case to me. I would much rather see an bool SuperMarket::inStock(item_t Item, int quantity = 1) that could be used for any item in the store.
