Doing the dishes seems reasonable, I behave as a guest in an Airbnb.

If there's a $150 cleaning fee? Not really. Sure, I'll throw a few dishes in a dishwasher and run it. But it's not like I'm staying in a friend's condo for free.

Do you charge guests in your home $100/night to stay there?

I wonder if this is a chicken/egg thing? Host are charging this silly fee because guests were not cleaning up after themselves?

Like at a cafe, it's socially accepted that you put away (bus) your finished utensils.

More than likely but that's not the point. If I stay at a hotel and I don't clean up after myself, I won't get charged a fee.

Just making sure I’m understanding you, at cafes where you live you clear your own dishes?

I haven’t encountered this before.

You don't do your own dishes but it's common with counter service to put them in a designated container and to throw your trash out.

That what I mean - I haven’t encountered this.

I’m way down in New Zealand.

There are almost certainly automatic machines for both of those. Throwing the sheets and dishes into the washers before leaving on your last day isn't an unreasonable request. It only takes a few minutes.

(That said, fining somebody hundreds of dollars for not doing that is unreasonable for the same reason that the request is reasonable; because it's an easy thing to do.)

The question of reasonableness cuts both ways: the high cost for the Airbnb unit plus the added fees including the cleaning ones, and the lists of guest to-do items upon check-out. The two combine and quick it becomes the feeling that you're paying a lot more than a hotel and yet have a lot more servicing to do yourself. If there is a very high cleaning fee, it becomes increasingly unreasonable to ask a lot of your guests to spend time cleaning everything before they leave.
