My job gives instant dismissal, no appeal, no pension if we're found to have alcohol in our systems. I've seen the results of too many folks who said 'I only had the one, I'm perfectly OK' and ended up as murderers.

When I'm working, I'm in charge of several bits of lethal machinery, there is no room for error. When folks drive, they are also in charge of a bit of lethal machinery, there should be no room for error there either.
