You should not let these instances get you down. Besides the ad lib from comedians (Spirit Execs must love it anyway - no such thing as bad press), the rest is just pure ignorance.
Your average John or Jane Q. Public is so out of touch, so naive, sheltered, oblivious and desensitized to reality - their pets should "walk" them. You see it in the terminals, on the roadways, in restaurants and grocery stores: They walk like zombies. Danger shocks them into even more of a daze - to the point of paralysis. On the highway, they will faithfully follow the car in front of them right into a crash - because they're not paying attention. People are so caught up in the "suburban rat race" they've forgotten to look up (or around) - and think critically - they are walking victims.
So, to hear someone complain about an airline, or any product for that matter, is par for the course - they have nothing better to do.
