One way is this:
Many factory machines require that the margin of error be within a certain range.
Suppose that one factory, which cuts wood into planks 10 centimeters long, has a margin of error of 2 millimeters. This would mean that the planks could be, at a minimum, 9.9 centimeters, and, at a maximum, 10.1 centimeters.
Absolute value would be used to determine whether the machines can cut the planks within the factory's limit. This, overall, could save you time- instead of having to measure each plank- and money- obviously people would not be happy if their planks were not aligning correctly!

A real life example for the absolute value function is a football field. Even though the center of the field is labeled zero, you wouldn't say you ran negative feet if you went backwards..
You can get the absolute value of a complex number by using Pythagoras's Theorem, which in this case is: absolute value (i.e., distance from zero) = the square root of (real part squared + imaginary part squared).
