Which sign says it best? - Help!

I'm staying with Nari again in Indonesia, and guests keep piling up their dishes in the sink.

Obviously, it's annoying.

For some reason, I take offense to it because I know they expect Nari's sister to clean it, just because she's paid to clean the rooms.

But I take get defensive about that and don't want her sister to clean them.

To me, it's treating her as if she's just a servant and not an actual human being of equal importance.

And it's not like she gets paid extra to deal with extra crap.

Anyway, I told Nari I'd just make a sign for her so that guests will be reminded to wash the dishes/realize it's expected.

She said, "No! If we tell them to do dishes, someone will leave a bad review. I'm scared."

For those of you who travel...what do you think?

Would you leave a bad review if a hostel/hotel had a wash your own dishes sign? Or an apartment that you're staying in for a couple of weeks- 1 month?

For me, I don't think it's a big deal and wouldn't leave a bad review over it.

But that's just me.

Maybe I'm wrong.

In case I'm right, though, I want to help them out by making them a funny/interesting/effective sign.

After we tackle this one, I'm going to have to make a "wash the sand off your feet" sign, next.

But for now...dishes.

Which sign is the best? Most effective? Least offensive?

Maybe say love, other guests. or something. Haha Nari would NEVER let me write "Love, Nari" 😁

P.S. All of these pics were straight up jacked from google images. I'll admit it.

Double P.S. Thanks for sharing your opinions!
