Some Marriage Certificate queries

I have just been looking at this certificate again and have a few queries



Is the groom's occupation "Temporary Civil Servant"?...seems a bit odd.

Why would the bride's father's details have been ommitted?

Next to the witness Henry Oliphant's name is written "A K Platt" - I had thought this meant "otherwise known as Platt" - or is it that there was a 3rd witness called AK Platt?



Thank you

Joan
