That guys jeans were gone way before he snagged a thread on the table. Its usually from carrying keys or a wallet in a front pocket as nuch as what's going on with the outside.
I used to wear carpenter style shorts around the house in summer...the ones with the hammer loop on the outer thigh...at exactly the height of my kitchen base cabinet pulls. I eventually had to cut the loops. I couldn't go a full day without pulling a cabinet door along with me or worse yet getting yanked to a stop in my kitchen. My builder told me the same issue caused a kitchen install crew to drop and crack a big slab of granite at one of his sites.
