Here's my difficulty. I appreciate what you're saying, and those are the theories that apply when there's a user fee. The user fee is usually predicated on an individual's wanting a certain service or program, whatever, so the individual chooses to have that and pays the money.
In this case, there are 10 trucks lined up, and I'm one of the unlucky ones who gets chosen. Now I'm out a minimum of $1,000. If I have a small vehicle, that could be my whole day's profit—if I've done absolutely nothing wrong, there's nothing amiss, yet fate grabbed me. What if I get grabbed again next week? I'm out another $1,000.
I don't understand this business. You're being checked for security—you haven't done anything yet, we're just doing our job—and you're going to start ponying up for being unlucky enough to be pulled out of the line.
Do you appreciate that there seems to be a prima facie case of unfairness here?
