OK, I know this is going to sound odd, but pets are a humanizing influence in public and commercial spaces.
Here's a good example. Passing through LAX recently, I noticed this lovely little dog park. It has a water bowl with a spigot, a small grassy area [OK, artificial turf], and even a fake fire hydrant. It's a nice little spot where pet parents can take their canine for a bio break during travel.
This space is actually nicer than the space designed for human smokers.
I really loved seeing this, I thought it was a brilliant addition on the part of the airport planners. Not travelling with a dog myself, I have no idea how functional something like this really is for a panicked canine that's been tranquilized for air travel. But it seemed like a real effort in the right direction and it made me smile.
