Worst job was my first one. Some friend of a friend of a neighbor had a carpet company. For like 15 years, they had taken every remnant they cut off for carpet, and thrown it up in the attic of the building. Then they finally decided they should figure out what they had up there and catalog it, and decided they needed a 14 year old kid to do it.
Well, the attic had no windows, no airflow at all, and was about 120 degrees. I was supposed to roll out a remnant, measure it, tag it with the dimensions, and roll it back up. You could barely breath, I'm sure the air was thick with fibers. And there was no staging area, so you were constantly trying to roll carpet out flat, but there was no flat, just mounds and mounds of carpet to climb over. One day I finally decided to figure out how deep the pile was, I dug like five feet worth of carpet without getting to the bottom, I pretty much gave up. Would measure a few in the morning, and then just try to lay absolutely still the rest of the day and try not to get heat stroke. Pretty boring in the days before phones. I would rearrange the ones I had tagged to look like I was making some progress. I definitely felt bad for taking their money ($3/hr or whatever), I would have happily quit but I was too embarrassed to.
Best job I ever had was working the grill in a hot dog/hamburger restaurant for two summers in college. Yeah, it was filthy and greasy and I would have to put bags of ice down my pants to keep from nuts from being 160 degrees, but I loved it so much. All college kids, met my wife there. I seriously couldn't wait to go to work every day.
The social aspect obviously wouldn't be the same LOL, but would quit my job today and go back tomorrow if I could make my salary doing it.
