Jokes on the Renter
However, it is a bit overzealous to contact an Airbnb owner and request a new sponge because the one currently there is a little soiled. It’s more likely just to go out and get a new sponge.
But, on the other hand, it is even odder for the landlord to return with a filthy sponge rather than a clean one. This landlord may be trolling this individual for being challenging to rent to since there’s always the chance they are trolling this person.
