In the late 90's a local glass company sold out to a national chain.I stopped in after the new regime took over,pretty much the same thing,all the workers stayed,and the price of an A windshield stayed the same.Only difference was the office help.The girl did tell me there would be a $30.patterning charge for each piece.I already had wood patterns for all the glass in 30-31 A Coupes,Tudors,and pickups.I had rescued them from an A guy that died in the 70's.I handed them the windshield pattern,and the girl said this will save us some work.I went back the next day to pick up the glass,and put my pattern and piece of glass in the truck.She handed me the bill,and it had a $30.patterning charge on it.I pointed it out to her,and said,I think you made a mistake,you didn't pattern anything,I did it.She said,no,all custom auto glass gets a patterning charge,you have to pay it.The office manager came out,and he said the same thing.He wasn't happy about it,(he was really on my side).I brought the windshield back in,and leaned it on the showroom wall.It was wrapped in cardboard,and I wrote Model A Ford on it.I left it for them.A friend went to them with the glass for his Rockne.8 pieces,perfect patterns.I had warned him,and he did figure on paying the patterning charge,but not on every piece.Four of those pieces of glass were identical,so they wanted to charge him 4 times.He didn't have it done there either.
