Due to Covid19 I had to cancel a work trip where I was planning to stay at an Airbnb. Even though there were stay at home orders for both my state and the state I was traveling to, I wasn't able to get a full refund for my reservation. The condo owner gave me a full refund (even though he didn't have to), but Airbnb wouldn't refund me the "processing" fee - which is all done by a computer. I find this practice very un-ethical in the circumstances that we're in right now.
