mm,

Computerized inventory needs to be deigned to include theft and damage. A
while back I was at Lowes shopping for a 90 deg stove pipe elbow. There was
one mangled elbow on the shelf. There were 3 elbows listed in their
computer. The store clerk couldn't find the elbows and left the damaged one
on the shelf. A month later I looked again, out of curiosity, and they still
had one damaged elbow on the shelf.
