I took in proof of Susan's death to the local JobCentrePlus, as instructed by the Registrar of Deaths.
The conversation went:
Me - "I've come to tell you my sister has died"
DSS Advisor - (offhand) "Yeah? So what do you want from us?"
Me - (shocked silence) "An expression of sympathy would be nice ..."
At which point, Advisor's Manager stepped in and took over.
