Today 12/7/2021 observed a window postal clerk being not so nice to a customer who was trying to mail a package and was given a hard time because he was not filling out the paperwork to the clerks satisfaction. She was going back and forth with him and he was trying very hard to be nice but she made him feel like he was incompetent. Finally he left and I could see he was annoyed. She then called me over and once I got to her window, I asked for a book of stamps at which time she now beckoned for another person to take something from him which took more time than just a second and lasted much longer so I got back into line and waited until another clerk came in and took care of my needs. I don’t want to think that she was being prejudice and a racist but it left me very much annoyed and overlooked.
