Sawyer Luck's final test

It's January 2'nd and we've got a sunny day in Paris and Monica is feeling a little better. This is it. We've going to Lyon today, ready or not. I head to the airport and our last box is there. Definitely more beat up, but it doesn't look to have lost anything. Next stop is Hertz for our car. Here the agent tells me they are out of my reserved car. Would I please accept a free upgrade to a mini-van? This is the biggest stroke of luck ever. Barely suppressing my giddiness at this turn of events, I protest that we're driving to Lyon and the gas mileage will be ruinous. Oh, it's a diesel, that's cheaper here, it should cost about the same. I'm about to sign the bill when I notice it is about $75 more than my quote. While she and her supervisor work at getting the price down I look around and find an example of what we call "stupid french rules." These are laws or rules that make no sense to us. In this case, there is a notice that the car must be returned full and that *you must present your receipt from the gas station* as proof that you filled up. How is a receipt any proof you filled up? Couldn't you just pump one gallon? That might be all you needed to fill up. It still seems like they have to check your gas gauge and possibly charge you later. While I'm thinking this, the supervisor says "Aha!" and they have fixed the bill. The problem? It was changed incorrectly and only had me having the car for 2 days instead of 3. I think I must have misunderstood so I confirm that renting the car for 3 days is $75 LESS than renting for 2 days? "Yes." Again, this makes no sense to me, but I will go along with it and speed off to pick up a stunned Monica and the rest of our luggage. "How did you get a mini-van? I tried all the rental companies to get one and they were all gone!" I tell her I don't know, I had no choice, they forced it on me. My poor wife, she is forever trying to get me to be a better travel planner and Sawyer Luck keeps interfering.
