Called in to give an estimate on the way home, three bed semi in a reasonable area. Nice lady in late 50's, obviously quite religious judging by the various icons/pictures knocking about, just moved in a week ago.
Standard 'moving in' jobs list as we wandered about the house, until we came to (what had been) the airing cupboard.
" I don't know what they have done in here" she remarked as she opened the door.
Entire interior lined with heavy duty aluminium foil, three batten lampholders above three slatted shelves :-)
She was shocked almost to the point of hysteria when I told her why I thought it had been done :-)
