When I worked for the Govt. as a contractor, the welders where total, so called "rough necks". They bragged all day about how much they partied the night before, were tough guys 'cuz they could drink all night and go to work on only 1 hour, or less, of sleep.
One morning a "rough neck" was dumping a huge pile of plate with a front end loader. He never saw the guy in front who was supposed to be ground guiding him, the ground guide wasn't paying attention and was so glassy eyed it's wonder he even noticed his leg as it sheared off when the stack of sliding plate hit him.
Of course they do an automatic piss test anytime there is an accident, no matter how minor. The operator blew over, the ground guide, now missing a leg, was over and his supervisor (who had to test 'cuz the director said he smelled like a brewery) blew over too.
Yep, pretty tough. Not being able to support your family and pay your bills 'cuz ya got drunk and lost your job.
You can cuss me out all ya want. I have absolutely no tolerence for intoxicated people. You want to starve your brain of oxygen go ahead, I won't stop you, but you better not do it on my time. The day I stopped drinking was the day my brother-in-law had to be identified by his dental records because of a stupid nurse who was late to work, in the morning, drunk as fuck.
