Sometimes I relate that to laziness...you can indeed think of the next person who is going to use the toilet, but if you do so, you will need to get an extra roll of toilet paper, set it up, all for someone that you don't know and brings no direct benefit to you. Things do stop there if it happens, lol.

Reminds me of someone who actually clean up the lint filter of the drying machines before leaving. I don't remember his face, but his actions told me that one single extra step of being mindful and doing some good can bring impacts to others. At least I'm actually deeply impacted by that, it must be amazing to be someone like that.
