I mailed a check in the curbside mailbox at the Warrenville PO and forgot to stamp it. I didn't realize it until I returned home and saw the stamp. I went to the post office to see if there was anything I could do and the representative actually went out to the mailbox and retrieved all the mail in the snow. Then we looked through the letters and found mine and stamped it. I am so impressed and so thankful. She actually thanked me for opening the doors when she was carrying the mail box. I just have to say --- WOW!
