Shitters without accountability.
If you made a messy boom-boom in a public toilet, you flush that down. In fact, you wait around to make sure it made it down. You flush again and again until every last speck is gone. I don't care if it takes you 3 hours of standing in the stall staring down into the bowl, you make damn sure that you do not leave behind any offensive material for the next user. And if the pipes clog-up because your movement is so weighty, you stay put. You do not leave. You die in that stall knowing that this is your punishment for eating rib-eyes for every meal for the last four days.
