I had an installer who was installing a blind and his drill slip, and he hit the corner of the window and crack the glass. He called me and then I called the owner of the restaurant. It was a really old and difficult window to replace so I was not happy about forking over Thousands of dollars A couple weeks went fine with no work from the owner. I was getting a little bit nervous so I called him and he kind of chuckled and told me to drive by the restaurant. When I did, I noticed they had plywood all over the windows so I stopped in and asked him what it happened. the day he was supposed to get the estimate an older lady on her car was in reverse, but it was in dry and she ended up driving through the cracked window so to quote dumb and dumber old people still can serve a purpose
