apart from the Police and legal systems, and their insurance.
Not applicable in Manila / Bangkok I can assure you.
So an AirBNB guest lights a tea light and places it on the brand new golden teak table then walks away. Comes back and has burnt a nice 1 inch diameter hole into the surface.
Then he checks out and promises to pay later because he is all out of cash now and has a plane to catch. Without a security deposit from AirBNB you expect me to call the Royal Thai Police over this ? Sue a foreigner who has just left the country over a 100 dollar damage ? Use the non-existant landlord's insurance ?
