you make a good point , but i am in Taiwan , that make things alot easier deal with people. also maybe a different rule apply here for the reservations on airbnb if anyone want to make a reservation need to submit passport or ID and pay online. i had a few tenants i found on facebook and i had to kick them out they were that sort of people because they didnt book online , people with bad intentions dont usually book online on airbnb in my experience ,they look for other ways like walk in some hotel and pay cash without ID , some desperate places will accept anyone.
in this part of the world people are a bit more polite if they need something they ask also for later check out , generally there is no crime here , i leave my keys in scooter outside for last 5 years and nobody took my bike , also i never locked door and elevator dont have any key either , also rooms are unlocked and your keys on the bed , people are moral here also its not a poor place. plus this place have cctv with facerecognition 4 on every corner , and its an island you cannot leave .
if someone feel sick for any reason i help them whatever it takes if i cannot help i would call ambulance. if someone die i have insurance and license and all departments come here check for safety , hygiene, fire man and public safety , if i dont see something they see it and i fix it , the chances are very slim or non also i have place full off cctv and people behave , but still complain , i let them take out the anger on me and i appologize so they feel special and get paid anyway , sometime i think of me as a punching bag that can take alot
