We, famously, had to leave our venue of 21+ years (and change the club name) when the new management of the Lewes Arms tried to charge us £50 for the room because they thought they could raise more selling food. The Elephant and Castle 200yds away welcomed us in. They don't charge a penny even though it's a Saturday. We have to move out occasionally for big money spinning events but we get plenty of warning.

(And the Lewes Arms still doesn't sell food on a Saturday night.)
