This could have gone differently.

Alex Nash, 5, is in debt.

After failing to attend a nursery school classmate's birthday party because of last minute plans with his grandparents, Alex received an invoice in his backpack.

Yes, that's right. Rather than asking Alex's parents in person to defray the cost or simply letting it go, the birthday boy's mom typed up an invoice and put it in Alex's backpack.

The cost of the party at the Ski Slope and Snowboard Centre per kid was apparently nearly 16 pounds. The professional-looking invoice (which lists the order number as "verbal") is for a "Child's Party No Show Fee" and even includes a place for tax (there is none).
