Greetings. We have used an ASL Interpreting service a few times over the past few months and have had a situation occur twice where the patron cancelled their visit with our library 2 hours before the appointed time. The service we are using requires a 48 hour cancellation notice or else we get invoiced for full service.
This question has two parts, so I will re-state them for clarity:
Is it legal to forward that charge on to the patron as they are the party who cancelled the service?
Answer: no.
