My experiences with Witherspoons outlets have generally been poor. The last time I was in one (in Sheffield near the university); at first sight it looked like they had an excellent range of cask ales. Then I went to order some; "No, I'm afraid we're out of that one". After I ordered three or four brews without success, I asked the girleen just what brews were actually available. To which she replied "I'll go and ask" For feck's sake!
I was chatting to a local man later in the day, and his opinion on how 'spoons managed to offer cask ales at £1.30 a pint was that they bought up end-of-batches due to go out of date and distributed them to the local 'spoons outlets and that was why they ran out of them almost as soon as they were tapped. They might only have a single keg of a particular brew and the places are often so badly run that they never seem to think of turning the pump clips around so the punters avoid ordering what's not available.
And don't get me started on the food.....
