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

I'll take any emotional support I can get.

My preference, though, is for the human kind. Though I very much respect those who have had it with humans and prefer an animal.

When you fly, though, you see that some people take liberties.

Awful, perhaps even deranged, liberties.

Airlines have recently tried to curb these liberties.

The absurdity, though, to which passengers can rise -- or is it sink? -- was described this week by United Airlines CEO Oscar Munoz.

Speaking to Bloomberg's David Rubenstein, Munoz told the tale of a recent case on his airline:

We just had a recent experience where one of the emotional support animals, wait for it, required another emotional support animal.

You see? And you thought you'd heard it all, with peacocks and other poppycock.

Munoz, though, continued:

It was a dog and a monkey. And somebody asked me earlier today, which one was supporting which and I don't know the answer.

Munoz explained that he's not against genuine cases. The problem, he said, is that the animal allowance is abused because it isn't regulated.

So often, passengers complain about almost every aspect of an airline's service.

Sometimes, they are, of course, correct. Many times, even.

But who'll be the first to deny that they don't, just occasionally, abuse some sort of rule, if they think they can get away with it?

Still, a dog and a monkey.
