- STSheldon ThomasApr 20, 20265.0I recently visited the Post Office and had a great experience thanks to Samuel. He was very kind, patient, and professional. I had quite a few questions about the shipping process, and he took the time to walk me through everything step by step without rushing me. He made what could've been a confusing process feel simple and stress-free. It's clear he takes pride in helping customers, and that kind of service doesn't go unnoticed. Big shoutout to Samuel-he made the whole experience a positive one. I'll definitely be back.

- RCRebecca CJan 13, 20261.0Rude new guy … don’t like his attitude definitely not the job for him. They need someone like Elizabeth she cared about her job and didn’t have an attitude problem.
- ESEd SpNov 7, 20211.0Seems like every time I go here it’s closed to staffing issues or the workers are on their lunch break
