I'm not clear on this because in a follow up post, she says she wanted to reschedule on Wednesday, but the hospital would not let her. In the OP, it sounded like they were rescheduled and I thought that was why she was on some list now. Or is that she didn't show up and that's why. I'm not sure.
I do not think the clinic should've remained open with those weather conditions so long as the patients who were scheduled were reached and notified (and fine, not notified of a closing, but given the option to reschedule which most would.) I'm just not clear what happened.
