Qantas rule leaves toddler stranded

The "moron of the day" award goes to Qantas staff in Christchurch.

So they have a rule that young children must be accompanied by someone at least 15yrs old. Sensible rule. Their dodgy website then sells tickets to a young child and a 14yr old. Then when they both turn up to fly, these rule-following morons refuse to let the young child fly. Do they really think that stranding a 2yr old away from its family is a better result than the kid being accompanied by an "adult" who is less than one year younger than their rule says is acceptable?
Some people on this earth still know how to use their brain and when to break a rule. These Qantas morons clearly do not.
