    Very helpful staff all of them , they try the best they can, to help you and help solve the problem, if they're are able to. Rob is a very nice and respectful USPS worker at the counter, all the workers there are good ppl and this is one of the best postal offices I ever dealt it . Kudos to the USPS staff of Mason City!
