We really could do with an updated Smoking and Public Health Act.
An unforeseen downside to the the original Act is that now you have to battle through a horrible fug of smoke whenever you go into or out of a pub (because the more thoughtless and uncaring junkies smoke as close to the pub doorway as they can get away with (often (illegally) in it, if it's raining), and, similarly, workers popping out for a smoke break often nip out the back door and light up right next to the ventilation intake, sucking fug right into the building.
We could really do with an update to the Act that also bans smoking within 5 metres of an entrance doorway or ventilation intake…
