The worse pub I have ever been in was one when I was a student and it was run by this landlord who treated all the customers so badly and the prices where shocking for drinks (Bear in mind this is a student town in Devon where drinks are normally fairly affordable so Londoners may be use to these prices). Ordered a vodka and coke once and nearly choked when the barman asked for £7. Then the landlord asked us all for ID, fair enough, saying it was only because our friend looked about 12. My friend Brum said "Well, I wouldn't quite say 12...", next thing we knew this guys was going "How dare you f**king talk back to me you bitch".... We never went back until it was sold to Hungry horse and got a lovely new landlady.
Best is this gorgeous pub in Lympstone that does the best carvery ever and has this beautiful garden you can sit in during the summer, and during the winter, they have a massive coal fire and Christmas they have masses of holly and give out crackers and it's just lovely! And cheap!
