So ... whatcha doin' there?

So I see this guy writing down notes near the truck, but there aren't any dials. He's just faking it, isn't he? He turns slightly so that I can see that he isn't doing anything of the sort, but rather, applying sauce on some sandwich. Yep! That's gotta be hard work, 15 mintues of solid moving levers, pushing butons, followed by wandering around. The trucks are doing it all. Ah, an industry where the entire staff could be replaced by robots. Hour number two and the workers are all circling the truck like they were working gawking at the athletic women running, jogging their day -- "Hey baby! I got a great city job! You look so fit (unlike myself) ..."

I think it would make sense to have the homeowners do it. It's not that tough. Park truck in inconvenient place. Raise ladder (lift), drop hose. Move miles of liner to wench and uncrease any areas. Start wench ... start pump, walk away. Process time 15 minutes.
