Interesting - most pub glasses I've seen are either English Ravenshead or French Arcoroc, so the nationality may not be an issue...

However, traditional 'tall glasses' are made with very thin glass, whereas most tempered glassware tends to be rather thicker - maybe that's the objection?

Personally, I much prefer the dimple barrel glass with a handle, which used to be the norm. I'm not sure why they fell out of favour... and they are much thicker than 'tall glasses'.

'Plastics' instead of 'glasses'... doesn't have the same ring to it!!
