Back in the early 70's went out on a call to a farm dog..sorted it and was asked to do some cattle PD's. farmer chappie liked me (for unknown some reason) as invited me for a drink. His tiny caravan was parked against a low pigsty block.
..in through the caravan door, across and out through the curtains, down some steps into a huge sunken room fitted out like a plush nightclub: red velvet seating, bars, snooker table, suspended lighting etc..
Apparently he hadn't been able to get planning consent for a house....
