I experienced this together with a friend while we were CS students. I went with him to a store to get several pieces of carpet. We needed each to be sized roughly about 1 meter by 3 or 4 meters. For some reason, both of us were quite worried about the long pieces not fitting in the car easily. Even when the person in the store had cut the pieces and they were on the floor in front of us we were looking puzzled at the lengths not fitting in the car. Then we were amazed to see our friendly salesperson stacking the pieces on top of eachother and rolling them up on the short end, creating a thick roll of carpet of about 1 meter long that would fit in the car without any issue. We were both laughing and feeling a bit ashamed that neither of us had thought of this simple solution and that we were really worried for nothing all this time.
