Just how tough is Security Glass?

I'm thinking that the guy in the white suit might want to seek out counseling.

He seems to have some anger issues.

To quote, ESG Glass is...

The UK's leading independent glass processor, toughener and laminator for the professional trade.

Don't know about their healthcare services for their employees, though. Then again, if the employees could just beat the snot out of their own glass every so often, that might help.
