I previously lived in Imperial. Barnhart post office carrier apparently doesn't like to deliver packages that dont fit in mailbox. I keep having to pick up packages at post office because barnhart carrier keeps leaving notes that " package was attempted to deliver". Varies reasons... no secure spot, snow on driveway etc. Never had this problem in Imperial ! Dhl and fed ex are great. They have delivered on same day that ups " couldnt". Ups also doesn't deliver either. Not happy. What's the sense of using chewy.com etc when I have to pick it up at post office anyway. (I may as well go to Petco if I'm going out.) I dont think they even try and certainly dont go out of their way to deliver. Everytime I have had to pick up my packages seems like the the post office has one employee. They even close between 1pm and 2pm for lunch... dont they have another employee to even cover for lunch? Ridiculous...Barnhart isnt that small but, post office sure is ..

Shame on our carrier. My grandchildren were in town so we let them pick out 3 bags of food for the post food drive Saturday. We even put it on a chair next to the mail box, in the postal bag with the others clearly marked. We sat on the porch, watched him pull up, look at it, put mail it the box and drive away. We yelled after him and watched him drive away. We will drive the food to Arnold food pantry where I am sure they won't be put out by picking up a few bags. Extremely disappointed.
