Pub bans Christmas jumpers - bah humbug? #BBCNolan

Now are you a fan of Christmas jumpers? Well an English pub has BANNED its customers from wearing them on the premises. Publican Alan Murphy of the Lion and Key pub in Hull is reported as saying "We have spent a fortune making this place nice and we feel we need this dress code, much in the same way some upmarket restaurants won't allow sportswear." So - Bah Humbug? Or a simple rule? Vinny gets the views of commentator Heidi McAlpin and etiquette expert William Hanson.
