I say good for you!!! I would also advise you to not feel guilty. Every family comes with it's own unique set of needs and issues so offering only one family something is not a bad thing.
Sort of sounds to me that the other family already got their "special" already as they got some extra time after closing hours and shared strep with you so definitley don't feel bad!
I think it is absolutely fantastic that you offered this other family such a wonderful freebie!!
