good customers get treated better.
occasional customers get treated "normally."
What's unfair about that?
Arithmetic:
I fly 20 times per year X $5.00 = $100 in taxes paid.
Someone else flies twice 2 X $5.00 = $10.
I pay $100, they pay $10.
I am a very regular, good customer. They are not. I get treated "special."
I am not "equal" because I am flying more.
The fact that I pay the same per unit as the infrequent flyer has nothing to do with it.
In theory, I should pay $4.00 or $3.75 per security check, if life were really fair. But since I pay the same, I get a shorter line as "compensation" for my being a "good customer."
Okay?
