While it is sad that they have to come to town for a funeral, there are always people in circumstances that are unexpected and sad. If they can't afford your place, they should find a place they can. I was recently asked to discount my rate from a potential guest who said "My budget is XXX and your current rate would make it XXX, I was wondering if you could discount your rate to fit my budget?"
To which I replied: "I'm sorry my listing is not within your budget. There are many options in the area so I hope you find a suitable option that is within your budget."
Then I blocked off a day in the middle of his requested dates to ensure he wouldn't book.
