Furniture on gravel.
A common scenario, below.
Furniture will sink unevenly. Soil was dug to place a brick under each table leg, gravel lapping to each. Voila, no bricks showing.
This is not a job for mere mortals, the slab of marble weighs more than my truck. After using the bubble level the guys are making sure the marble is also set equidistant. These 'small' tasks always blow my estimates of, "Oh that should only take a few minutes."
