@Jillian115 I wouldn't be at all surprised if a lot of these CS reps have been Airbnb guests, with bad reviews, because they failed to read the listing info, ignored house rules, and left bad ratings and reviews due to their own negligence.
If they don't know policy in their job as CS reps, they wouldn't know it as guests, either. Which could be a logical reason why they so often favor guests over hosts.
