Do you check to see if each property you book has an elevator before you book it, or do you just assume it?

But that's not even particularly relevant. Stuff happens. How about if the municipality interrupts water service to the hotel due to a main break while you are mid-stay? How about electricity interruption, say, during the blackout of 1978(?) (which would, of course, also take out the elevators)? Compensation due?

Ever make a mistake in your job? Do you compensate your employer/customer by voluntarily returning part of your pay/fee?
