Do People Concern Themselves w Driveway Vehicle Leaks?

So "yes," I do have moderate, life-long ocd. So I need to know if this issue is something that people just ignore, or whether it matters:

New, very expensive driveway installed last year for the first time in 20 years. Winter time right now with a thin layer of snow on it.

Friend of family comes over, knowing they have a profuse leak (in this case wiper fluid) and parks in our driveway, filling their fluid level before taking a member of our household out for an afternoon/lunch/etc. A monthly-or-so routine.

Their car is less than five years old, so the leak is unusual. But they are aware of it, fill it in our driveway (and spilling some in the process, pull out of our driveway when they leave for the afternoon, leaving a blue puddle in the white snow with drips all the way down the driveway.

They come back...I politely say "Hey, just a heads up, you have a fairly profuse wiper fluid leak" (pretending I didn't see them fill it when they pulled in) to which they said that they knew and a family member was going to fix it.

So MY thought was "Welp...if you KNEW you had a leak, and are fully aware we have a brand new driveway from just last summer, don't you think it would've been courteous to park in the street where it wouldn't leak all over our new driveway and possibly have it tracked into our house???"

Because of who this person is, I mentioned only the leak to them, as if I was trying to be helpful, but with luck get them to actually think about the fact that it's leaking on our driveway and that perhaps they should move their car.

If they even offered, I would've told them not to worry about it. And I'd still have to clean it up regardless.

I'm waiting for them to leave now so that I can go back out there and hopefully capture as much of it in the snow as possible so that the shovel can remove it from the driveway. We do have other people coming tomorrow and I do not want them stepping in chemicals that they then track through the garage and into the entry of our house.

Can people relate to this? I know this aggravates my ocd BIG time, and that I have a problem with ocd, BUT, don't people CARE about not making a mess on someone else's property?!???

Thanks.
