Absurdly Driven looks at the world of business with a skeptical eye and a firmly rooted tongue in cheek.

When it comes to airlines, rules are rules and they're strictly enforced.

It's just that sometimes strict enforcement is more pointless than trying to talk sense to a congressman.

When, though, do you decide that a rule is pointless?

Here's the tale of almost-3-year-old Ruby. She was flying with her grandmother, Stacey Osmond, from Nova Scotia to Calgary with Air Canada. It's a five-and-a-half-hour flight.

Now Osmond says she made sure to book seats nearest the washroom because kids, you know, have to go to the loo, sometimes with urgency.

But, as she told CBC, there was a problem.

"The second or third time I tried to take Ruby to the bathroom, the flight attendant told me, 'I can't have you coming up here anymore,'" Osmond said.

The nearest bathroom, you see, was in business class.

Osmond protested: "I said, 'She's a baby. I was given those seats by a booking agent for that reason, so that she would be close to the bathroom."

You know that this doesn't have a happy ending, don't you?

Osmond said that the next time Ruby needed to go, a beverage cart blocked the route to the back of the plane -- where the economy class bathroom was -- and Ruby wet herself.

"I sat there, still having to play with Ruby with a smile on my face," Osmond told CBC, "while I was just full of anger because of this woman, especially after she peed in her pants. I got some napkins off the flight attendant and I put them underneath her so she could sit on them."

Osmond says that the airline did offer compensation, including a 25 percent discount off her next flight and some toys for Ruby. What she wants, though, is a full refund and a personal apology from the flight attendant.

Air Canada didn't immediately respond to a request for comment. The airline did tell CBC: "We're in contact with our customer about this regrettable incident. We have no further comment."

I can imagine, though, that not every flier will agree with Osmond's sentiment.

There are those who believe that business class is just that, a place of (hopefully) quiet and repose.

Why, then, did Osmond's booking agent tell her that the business-class restroom would be free for Ruby to use?

Others, though, might see a touch of callous disregard on the part of the flight attendant -- an attitude that's been evident many times of late in tale after tale.

Who can forget the Delta passenger who was thrown off a plane for going to the restroom just before takeoff?

Where do rules end and discretion begin?

Wherever the airline staff decides to do, they do.
