Whilst the driver of a tube train recently got caught I wonder how widespread drinking alcohol on duty actually is. Right now I'm connected to wifi in Soho Square. This is next to a very large Crossrail construction works. Many of the workmen from Crossrail in orange or yellow hi-viz jackets etc. have their lunch there. Many are drinking from cans of strong larger. OK - its dusty work but ... I wonder how many workers have been killed on such construction sites from their colleagues drinking alcohol at lunch-time?
