*Comments below are not read by postal employees. Please do not post personal information.office, got there at 4:28, and lady at door says- "No sorry, we're closed". After all the rush to get there early, I get kicked out for being there one minute before closing
time. If I had her kid in my class, I know I wouldn't say "sorry kid, I can't read the last page of the book for you, times up." How rude of this employee at the Mercedes post
Office.
