I had that once, whilst i was at work we had a council man come around to do some measuring, and the IDIOT decided to put the end of his tape measure to the back of a shelf where i had eight built kits of different subjects, WHEN suddenly my wife heard a crashing sound from the room where i had this shelf. She give her her due rushed upstairs and into the room to see my built models on the floor complete with the shelf.
Okay he could not stop apologising about what had happened, he should have asked first if he could do this as the shelf was not affixed, as should i need to move the shelf at some point it was not screwed down, but the wife knew that i would hit the ceiling with rage (i did), but he did say in his defence that i should reclaim in money for the damages done, so i at the time i put in a quote for my inconvience, and give the council there due paid up.
But no money can ever replace that build as many of us feel that once built, decalled, painted the jobs done then onto the next project.
