    They have drop bins for prepaid packages. Plenty of parking. Great staff compared to other city post offices. I started my daily package drops at this location about a year ago. No problems the staff of two are always welcoming even after a full day that can be exhausting.(My drops are usually at 4:30)

    The lady behind the counter is very rude and unprofessional. I understand they are government workers, but it doesn't give them the right to treat people that way. Didn't get her name. I had pre paid packages that just had to be dropped off. The sign on the door said 5 people max capacity, I was the 5th. Stay home if you don't want to do your job.
