I don't expect skidmarks on the toilet, but can you believe I find them there?
Could you tell me a bit more about the skidmarks? Wow, that is something else.
For me, regular toilet paper seems to be enough to prevent leaving skidmarks.
I certainly agree that you shouldn't find skidmarks on the toilet. People should really be more responsible, and clean up the toilet if they make a mess. It's unsanitary and disgusting to just leave the mess for the next person to deal with.
If people use it, I think it's natural for them to leave some mark. But yeah clean it up afterwards.
Messy toilets are pretty gross. That will be something to think about the next time use the toilet for sure. Letting others clean up your mess is not very polite.
