I was in the Dewitt post office yesterday to drop off a package around 11 AM. There were two women working the front counter. One of them was Angela I believe. I asked if I could borrow some tape to close my package and at first she said she didn't have any, then noticed my husband who is in there all the time and she then proceeded to look for some. While getting my package together, the conversation between the two employees was appalling. It was extremely vulgar. They used explicit language that was totally inappropriate. I was extremely disgusted. Needless to say I will not be using this post office any longer.


Do not go here for passports. The person who takes care of them is not always there between the posted hours.
