Not receiving Facebook page check-in notifications

I manage a Facebook page for a pizza restaurant and occasionally I receive notifications of check-ins from customers on Facebook. However the other day my sister checked in (she typed text and clicked on the location marker where she selected the restaurant name) and I never received notification. I am wondering why this is? I also wonder how many other check-ins I have not been notified of?
