Congress Heights Post Office: 400 Southern Ave SE, Washington DC 20032 Saturday, 10 September, 10:30 am, hand written note placed on main entrance glass door, which was locked, said, Closed be back at 9:45 am. There were 5 people waiting on the steps in front of glass entry door, unable to get in. One person could see movement behind the counter. and knocked on glass window to get attention. No one from the back of the post office came forward, A person called 911 to have a "Welfare" check for the post office front counter employee. One person said he saw the front counter employee say she was leaving and would return in 15 minutes, then saw her leave in her car, which was parked in the back of the post office. Four police cars arrived first, then while the police were still on site, the person waiting said, here she returns now in her car! The police began to leave. I flagged one police car and asked if they did a report concerning this incident. I was told, No!, A person should not have wasted their (police) time, a business can "close" whenever they want! This habit (this same incident has happened more than 1 time by the same employee) by the Post Office employee should be investigated by the Post Office, and corrected.

I was notified by my neighbor that he had observed the mail carrier leaving mail outside on ground again. He has informed me that he has pictures and he has picked up mail from the yard where it has blown off the porch from the wind or put it in the slot when it was raining. (There is a mail slot for it to go inside.) When I arrived today he was angry and stopped me again. Both my and my neighbor’s mail were wet from rain and laying on the ground with a rubber band around it. We sometimes get each other’s mail and we neighborly walk it to each other’s slot. Not sure why this is happening but would like to have it addressed.

This location needs more tellers it takes up to 20 mins most visits to get to the window and be serviced. I've lived in this area for 3 years and nothing has changed.
