I think it's more like planning a hiking trip with your friend. Your friend payed an nonrefundable deposit on the camp site and then breaks their leg the day before. They are out a ton of money, they are injured and layed up in bed but you are mad at them because you are minorly inconvenienced. On top of that they said you can still use the camp site if you take his brother who is cool you don't know quite as well.
In necessariis unitas, in dubiis libertas, in omnibus caritas
