Re: beers mixed
Down here more pubs are Greene King than anything else. Abbot Ale gives me cracking headaches but tastes lush, so often get half Abbot/half IPA. I've seen it offered as "house special" at one country pub but always get a funny look if I order one anywhere else.
Other than that, drank turbo shandy or cheeky vimto, i.e. Smirnoff Ice/Lager and Port/WKD Blue regularly as a student. Not for a few years though
