The last time I was in a Davy's, for reviewing purposes as I don't like them, I asked for a half and the manager served it in an over sized half glass and told me the measurements where exact and he couldn't fill it to the top. Hmmm!
WE ARE THE BREADMEN - UP THE BEES
I'll drink out of pretty much anything, but I have never been overly keen on the straight glasses you find in Wetherspoon outlets. They're suited to lager perhaps, but not ale. I do agree with Strongers: there is nothing worse then drinking Guinness out of a lager glass - or vice-versa, actually. I recall drinking lager out of a Guinness glass on more than one occasion.
