Spirit isn't known for great customer service. A couple of airlines no longer outsource CSR to India.
An airline that charges for assigned seats can't fairly waive that charge for some passengers. What percentage of passengers on a flight to MCO fly with a child? Do you think it's fair to waive assigned seat charges for half the passengers?
I don't think you're being honest with us. You thought you could talk Spirit into waiving the seat charge. You were not only told NO but your request to speak to a supervisor was refused. It's certainly possible the foreign CSR, reading a script, could have been "nicer" but it's probable you wouldn't have been satisfied with any response that didn't include waiving the charge.
Spirit expects passengers that want to sit together will pay the fee. I'd certainly hope most parents with young children are in that category.
edited to add You started the thread looking to rant. Most of us think it would be unfair if Spirit exempted some passengers from the charge. I'd be "ranting" if half the plane got the fee waived but I had to pay for my seat. SW moved family boarding from pre-boarding to mid-boarding (between the A and B group) because many other passengers thought the old arrangement was unfair.
