Where the hell did the idea of tipping your landlord come from, anyway? I've heard a few people in recent years bring it up as if it was an actual thing, and I'm just like WTF?
Now we have people killing themselves in attempts to “prove” that the Earth is flat.
Never doubt the ability of satire to fly over people’s heads at 10,000ft, and for those people to swallow that satire uncritically; hook, line, and sinker.
There have been some smaller landlords who have actually asked for it. If it has been successful for them or not I cannot say. I would assume not, it's fucking asinine.
