The Stores in a certain college where I once worked
insisted on checking
every delivery to make sure it was complete. I couldn't undertand why one
or two ICs in several orders were faulty, until I realised they took them
all out of the tubes to count them :-(
Intel or AMD had a similar problem (huge yield problems) because of an
overzealous clerk counting silicon wafers by hand. By *touching* them.
