wrong way to tighten the windows
How does a handyman hired to install my windows end up cracking them in the process? After fitting the windows in, instead of doing the smart thing, which was to take them down, tighten them and then re-install them, he decided to cut corners by tightening the windows with a hammer with them in their fixtures. Well, his hammer hit one of the panes in the process, and, well, there you have it. At least he was a nice chap about it and actually offered to buy back the windows since he damaged it.
