Pipless wonders

Is it any wonder that British chainstore Marks & Spencer is in trouble? They are preparing to sell pipless clementines. They think they've done it by making sure bees can't cross-pollinate their seedless clementines (clemenules) in Valencia, Spain which have been grown six miles from the nearest seeded variety.

Can M&S really be sure that the bees again haven't read the books and have flown further from their hives than expected. We'll see when the fruit goes on sale in December. Will there be a rebate for customers getting the pip?
