Will Leave You Graphing And Laughing
I had a summer job in the inventory department of a furniture store that sold items in flat-packs for ease of transportation. We had lots of problems with customers believing that flat-packs were magical and could make large furniture items fit into tiny cars. While we made a good faith effort to load their purchases, it was common for us to give up fighting the laws of physics and ask the customer to return with a larger vehicle.
One day, a lady pulled up in a sedan to pick up a dining room table. She noticed my skeptical look and showed me a sheet of graph paper where she had diagrammed exactly how the table would fit in her car. With the large tabletop unboxed, it slid in at precisely the angle in her diagram and the trunk could be closed without issue.
I was heartily impressed! I never saw Graph Paper Lady again, but I think of her detailed diagram any time I see people trying to fit oversized items into their undersized cars.
