I have this fantasy of winning the lottery and calling up the Bishop's office and saying I need to speak to him
right now.
And when the receptionist says, "Oh, yes, and who do you think YOU are?" (not that she would ever actually say anything so rude, but, hey, it's MY fantasy), I respond "I'm the woman who just won $300 million in the lottery and I want to build some schools!"
I suspect your call would be put through immediately. If the Bishop was not there then my guess is they would page him. You would be taken care of.
