Then she's got a few choices. She can toss her chairs and get new ones. She can hire someone to fix her old ones. Or she can live with her old ones until they break and she's forced into acting -- and that can mean she jury-rigs hers for a while.
If she wants to live with her chairs held together by rubber bands or whatever, well, she's a big girl and can do that. If she can afford to pay someone to fix them, then someone will get a paying gig out of that, so good for them. Buying new stuff means her old stuff often ends up in a landfill (unless you live in an area where people grab the big stuff out of the trash -- I do, so a lot of stuff like that is recycled. But not sofas or mattresses as there is always the fear of bedbugs). Still, buying new stuff stimulates the economy. Her choice.
But don't do anything for her (or anyone like her) for free. "Sure, Sue," you say, "I can swing over tomorrow after work. Materials will cost $13.80 and let's see, my time will be rounded up to the nearest hour so let's call it $50 for my time. So, $60 total. See ya then!"
