While I'm at it (and likely ignoring something that's brought up already) -- dogs on planes.
I am a huge dog person. Love 'em, and though I'm partial to actual dogs, I'm not opposed to those kind of yappy faux-dogs (you know, the lap dogs, the teacup breeds, etc. -- might as well get a cat at that point, but to each his own).
I'm also a big proponent of service dogs - not just for actual utility to help the blind, people with seizure issues, etc. but even for anxiety and stress.
That said, we've gone WAY overboard with dogs on planes. I saw a 80lb+ rottie on the plane the other day, which couldn't have been comfortable for either the dog or anyone else in that row. And there is no way -- as nice as rotties can be -- that the dog was an actual service dog.
Since when did it become a god-given right to travel with your pets, especially at the inconvenience of other passengers? Leave the pups at home, people.
