We just recently went on vacation. We all had a fantastic time. One of the things we agreed to do very early on in the trip was to split costs equally. This was mostly to help out my single brother in law since the rest of us were going as couples.

Anyways, long story short, the trip was great. No issues whatsoever. Food Budgets came back and they were basically relatively even anyways so no concerns there, but then after the trip was over, we were give our totals to pay for the car rentals.

My wife and I Split a car with her parents, and the two brothers split their rental.

Our rental came out to be somewhere around 850 CAD after conversion. Their rental came out to be around 1350 CAD after conversion.

Long story short we were expected to pay a rounded up figure of about 640 dollars for our rental after the totals were split 7 ways. (The numbers here are slightly off, and not in my favour).

Anyways, I was quite pissed off about this, because their rental was almost double the cost of our rental and I inquired as to why. We got our rental with our own insurance, they payed for their insurance with the rental company as well as added on premium roadside assistance and got a higher model van.

Long story short, I was pretty pissed off, and my wife didn't want me to say anything but I didn't feel right. So I spent the majority of the day discussing it with her and figuring out a more "fair" way to pay for these rental cars since we were essentially paying over 70 percent of our own rental.

I knew we were going to have to help her brother out and that was only fair, so I decided that we (myself, my wife, and her parents) would pay off the "missing quarter" of their rental car (they only had 3 paying adults in that van as opposed to our four) and then pay half of our own vehicles. It was a difference of I believe , 22 dollars per person or something, but it gave me piece of mind knowing that we were at least alleviated in some way.

So, once I presented this plan, there was a long day of silence, and her father responded with "everyone pay the same amount as we would pay, and we will pay the difference"

This pissed me off even more, because now I looked extremely petty (even tho I still had no problem absorbing a large portion of their van) So I just said NVM, we will pay it and I immediately sent out the initial amounts.

Still kind of irked about.

AITA?
