But TF2 micspam aside...the assault of people with beer glasses goes back a while...IIRC it was in a Victorian music hall play, to do with a young orphan girl who sang at pubs but was eventually killed by a thrown beer glass...cheerful ending but that's how they wrote them back then...I'll look about for the name of the play but I doubt I'll find it.
At least glasses are made of better quality glass these days than the giant clunkers of the 19th century.
Do love the old tankard designs though.
EDIT: Oh, and Sky, I don't know about inner-city pubs, but all the ones I've been in have served beer in normal glasses. Glass pint mugs (my favourites) are also still about in some places. I have a Carling Extra Cold pint glass right next to me in fact...sadly no Carling in it though
