Inn for Trouble (1960)

After 25 years working at Belcher's Brewery, Alf Larkin is given a pub to manage. But the Earl Osbourne is in trouble, mostly because the Earl himself has a tradition of giving his own very quaffable beer away absolutely free once a quarter. The Larkins come up with various tricks to gain custom, not realising a proposed new road means the place could soon become a goldmine anyway.
