"Why should the government meddle in this business?"

Because the airport is government property for one. Second, they are a licensed business, there are dress codes, hygiene requirements and all manner of other rules. Service dogs are allowed in restaurants, on buses and most anywhere else these days. Why not in a muzzie cab?

And I'll wager that the ADA covers the service dog issue.
