I got to the post office at 5:58 and they don't close until 6 o'clock. Upon getting there, the front door was already locked. I went to the side door, also locked. However a lady was in there walking out at the same time and I told the man that was letting her out @ 6:00 on the dot, and he called me a liar. Blatantly. However there was 2 other men that came at the same time as me & they tried explaining as well, and he didn't believe them either. Worst experience ever at a post office. If someone could please contact me @ (630)926-3369 regarding this matter, I'd greatly appreciate it.
