Oh, forgot to say that the nice people behind the bar were happy to fill my Sigg bottle with beer for a pound a time, which I think is the best price I've paid in this country. It's a litre bottle… perfectly acceptable Thwaites Lancaster Bomber, for the most part. And I did tell them it's nearer two pints than one.
Also forgot to write the post to which this is an addendum, come to think of it!
