Horrible service! Waited in line with other customers. When my turn came up I was told to move to the side and they would get some one to get my held mail. I waited and I waited. Finally the same clerk that told me to stand to the side asked for my ID and got my mail. I waited in line like everyone else and should NOT have been bypassed since there clearly was no one in the back to help out. Retrieving my held mail didn't take any longer than any other service.
