I've seen many people at the post office that weighed and printed labels, then have to re-do them at the post office because they were wrong....

Usually the weight doesn't correlate to the post office scales and they readjust the price...

Guess I'm lucky that my digital scales are accurate comparing the weights to both the PO and FedEx scales. Now if they're not accurate, yes, they'll have to do the adjustment. I boxed a fender to send by FedEx and measured it as accurately as I could; FedEx said the measurement was off and billed me the extra. Can't win them all I guess.
