M : can you explain this rejection
Ii : there must be something wrong with it
let's look at the rejection slip
yes, the dimension between the pads is out of tolerance
M : How much is it out
Ii : about three millimetres
M : Oh, no there are thirty in the batch. Are they all like that?
Ii : No, I've checked the others and they're all acceptable
M : Are there thirty in there or thirty-one?
Ii : i'll check again,just a minute. one,two...twenty-nine,thirty-one.
M : Oh,that's good. We're all right then. I don't know what happend.
Ii : The machinist probably used a reject when he set his machine up. Then he probably put it with the other parts by mistake
