What are these checks and scrutiny and how are they applied in the time available? Given the time available is not great ("I'm on the next flight") and the amount of money is modest if humans are involved I'm intrigued to know what could be done that $45 would cover.

what the fuck extra checks and scrutiny could they possibly need? They already go through an x-ray machine and get molested before we get on the plane, "real ID" or not.

Got a bridge to sell you

Bullshit. Also not legally required.

I'm almost positive they get paid the same at the end of the day either way and the $45 just lines the pockets of someone on the top.
