You guys are the best! A mailwoman noticed that my package was misdelivered to the wrong house and went so far at to ring my doorbell to let me know. SHE IS AWESOME, and I greatly appreciate her and your services!


Our little local post office has always provided EXCELLENT service. The clerks are usually friendly and very helpful. The service here is much better than the larger nearby Westmont post office, and the lines are usually shorter. It is a small post office so there is often only one clerk on duty, but sometimes there are two. So if you are in a hurry, don't go during lunch hour or right after a holiday or 3-day weekend.


I went to the Clarendon Hills post office in the past months at least four times, every time I went only ONE postal clerk was present and the line was very long. Yesterday I went to the post office, the line was out the door, people were standing in the cold, freezing, elderly folks as well, standing there with their masks on and only ONE clerk was present. I almost fainted in the lobby with these mask procedures, it was too hot inside, face covered, and the line wasn't moving at all. It felt extremely uncomfortable. In times like these and Christmas so close, at least two clerks should be present and with all the scientific findings and statements from professionals mask wearing is absolute and should be up to the individual if they want to wear them or not, and not enforced by the post office. It's UN-constitutional!
