good welding job
Learning from all the old hands after being hired as a new, green hand at the oilfield/agriculture repair and maintenance facility I started my career at.
bad welding job
Finding out I was to be treated like crap and do every lousy job that no one else wanted to do because I WAS the new, green hand. Nothing like being in that nice warm shop on a day when it was 20 below wind chill factors outside and having the boss tell me I needed to go power-wash the cow manure off a bull-dozer from a cattle feed-yard so I could weld some cracks on it! That meant I got to fight a high pressure water hose, and dodge cow dung as it shot back at me while getting soaking wet in the biting wind. It was so cold I had to thaw my words with a cigarette lighter just to hear myself gripe!
