i went with my husband in monmouth, me 04259 post office & this employee by the name brenda smith is so rude to me as i was trying to send a package. i think she is not happy in her job she might as well quit... she is tell me why my package is heavy as she hv a hard time lifting it in the scale well i am willing to pay for it,. also if she can't do lifting under 10lbs she is not fit on her job as post office job needs some lifting on their work i think?
