And a Diet Coke please

You've been asked to design the layout for a shop inside St Pancras station. You know that this station is home to the Eurostar, therefore you also know that most passengers will be accompanied by a suitcase about half their weight and twice their size. Do you think:
a) We should really widen the aisles to allow for people's luggage
b) Let's make the aisles narrower than usual - people like that uncomfortable, suffocated feeling don't they?

Now, don't be fooled readers. Although common sense might lead you naturally to solution A, the correct answer is actually solution B. "But why?!" I hear you cry. Admittedly, the very same thought crossed my mind as I emerged from WH Smith having spent half an hour locating and purchasing a pack of playing cards which turned out to be designed for the visually impared. But on reflection, I have deduced five reasons behind this apparent lapse in judgement:

1. Being a security guard is boring
And I'd imagine that endless hours of entertainment can be had from watching us struggle with suitcases, while attempting to hide the condoms/sanitary towels/porn that we are trying to buy.

2. To create a moral panic
The Government has hatched an initiative to encourage public brawls in stations, in an attempt to distract the press from the worsening economic crisis.

3. Energy expenditure
The Eurostar's finance department have realised that the more energy people spend lugging suitcases around or fighting before departure, the more of their journey they spend asleep, and thus the less complimentary food they consume. Which equals more money for the powers that be to spend creating mass pile-ups at Waterloo by introducing spangly new turnstiles at every exit.

4. Profit
The clever directors of station shops have realised that no self-appreciating person will spend half an hour of their lives buying a pack of cards and will therefore buy something else as well. This might only be a diet Coke or a packet of Wrigley's Extra, but multiply that by a month's footfall and you've got yourself a nice Christmas bonus.

5. Because they can
Times are tough, and widening the aisles would set companies back a sizeable amount. So they don't. And we wouldn't dream of causing a fuss - we are British after all.
