When I worked as a postie
I was on the desk a fair bit. Our basic (unofficial) policy was that if they showed us a driving licence with the right address on, they got the parcel (though this was for recorded deliveries, not specials, which are a whole new mess of shit if they go missing). You still need the card though.

We did have one lass come in with her marriage certificate, since she'd only been married the week before and so none of her ID was up to date.

Generally we were fairly sensible, but they guy that worked the desk during the week was a complete arse.

Another hint: If you get one of the "insufficient postage" cards, then you can ask the bloke behind the desk to hold it up to the light to see if he can make anything out (though you can't take it or have him open it unless you pay). Also, around christmas, the staff get so tired of charging people £1.09 for the christmas cards slightly too big for normal letters that within a couple weeks an order has come through from on high just to let them have it.
