The Surrey Assembly Hall site of a sister turning up and working all day in high heels, the keys to the dumper trucks were a free for all, the utter stupid pointless waste of time that quickbuilds were haunt me to this day, someone holding a plank of wood, someone else marking with a pencil, someone with the saw and someone else walking off with the cut plank, the ultimate in inefficiency
Too bad about the old gent. He probably saw some Cob Webs in an electrical box or vault and stuck the metal vacuum cleaner hose into it. I'm guessing this is one experience they won't be using on the assembly stage.
It's easy to be critical but I remember one quickbuild where they were unloading a load of seats from a truck and instead of parking the truck close to the door, they parked if far away and formed a "human chain" and passed the seats a piece at a time down a line of 30 people instead of having two people unload it at the door. (of course it wouldn't have been as much of an "encouraging" sight to see if they'd have done it the smart way and it kept a whole lot of unskilled folks out of the way.)
