Back in the 70's I was in a club with my then boyfriend when someone groped at me. Nick remonstrated, mildy, with the guy who said 'so fucking what', broke his glass and shoved it in Nick's face.

Nick ended up with a five day stay in hospital, nearly losing the sight in his left eye and with one hell of a scar to show for his pains.

Trust me, once you've witnessed something like that you can see why plastic would be a good idea in some places. Even then there were certain pubs in North London that went over to plastic because of the problems with a small number of the clientelle.

On a venue by venue basis I can see that this would be a good idea. If it ever got to being mandatory for all pubs, then would be the time to show that your local doesn't have the problem.
