I wouldn't be bothered with that stop, let them call up and complain, this is how things get fixed at our building anyways. If you ask, they'll just ignore you because UPS management is trained to treat drivers like ignorant derelicts. So let the customer call up and chew out an OMS person, watch how fast you get your ID.
Only suits get the hard ID's here, as if that makes any sense. We have tiny little junky ones that look about as cheap as a middleschool student ID.
