This one makes me think back to my early 20's when I worked tha auto assembly line, worked a "heavy press", and for a while in the iron foundry. I would watch at the end of each shift as most of those under 30 would run to punch the clock while many of the older workers would go to the coffee machine first and stand and talk before punching out as if they really had no where else to go that was important and they refused to fight the parking lot traffic.

Reminded me of the months I worked second shift for a water bottling company less than quarter of a mile from my home as the crow flies. It was sourced at the local (ice cold!) artesian spring. How many bottles did I quality control the labels (toss them if they didn't line up right) and stand the bottles up for packaging. It was every bit the yawn you spoke so well.

I had to come back to this one. The use of the word tango is what catches me, especially after watching the ice pairs' dancers do their tangos - repetition, around and around and around, even music can wear one out. I've never worked in a factory, thankfully. Those last two words are almost a chuckle to "yawn expectantly" - irony at 8 a.m. Thanks, Jim.
