I've found I like Black & Tan. Half Sovereign and half Extra Stout. Very nice at ?2.01pp.
We have a temporary manager in our local whilst the managers are on holiday. On HS's instructions she will not serve a Black & Tan straight into the glass. She has to fill two half pint glasses with each, then pour them into a pint glass. i then ask for a top-up as the result is way under 95%.
I'm not in any way at all criticising our temporary manager. She is doing a great job. But Humphrey and his strange pedantic rules? Blimee!
