I love watching the workings of a construction site. It's a rough life, messing around with the soil and the dirt and the grime of earth-moving machinery, along with foul moods, colourful language, a great deal of swearing and yelling, and rough jokes.
Backache, sweat-blood-tears, tiredness, risk, teamwork, comradeship, laughter. Construction sites have it all.
It probably is - I don’t think the guy even opened the coffee jar.
