First there was the infinite improbability drive. Then there was the bistromatic drive. However, that had the downside that the inside of your spacecraft had to be attacked by interior designers until it resembled a restaurant, in order for the numbers to dance in the correct way
Now it seems that West London pizza delivery firms have figured out how to advance the technology still further, so that numbers can be made to dance in the comfort of your own living room, without any gut-wrenching makeovers.
Take, for example, this menu from Romeo's Pizza:
Med Large Super
Cheese & Tomato Base £4.95 £7.70 £8.50
Extra Toppings £0.50 £0.70 £0.90
Free Choice £7.50 £10.45 £12.95
where Free Choice is Cheese & Tomato with 4 toppings of your choice. Whereas if you do the same à la carte it would cost
£6.95 £10.50 £12.10
This makes no sense. Sometimes it's cheaper, mostly it's not. I think they must have cracked the secrets of bistromatics, and managed to decouple the numeric effects from the environment. Pretty soon I guess pizza will no longer be delivered by suicidal learner moped drivers, but suicidal learner flying saucer pilots. Duck!
