Your early morning clerk is very inefficient. I arrived at 7:30 to pick up a package, and your clerk had one customer ahead of me. It took her over 15 minutes to help that one customer, so I had to wait in an enclosed area for almost 20 minutes. At a time when we are being told to avoid closed spaces with other people this put me at unnecessary risk of exposure to covid-19.

This post office get away with murder Most of the town, and all the residents in the surrounding Lyons area do not have mail delivery. We all have to drive to the post office to pick up our mail. They consistently close the front desk and pull the metal barrier across the room well before closing hrs. Heaven forbid they work a few extra minutes. Although most of the clerks are efficient, there is a new one who does not know what she is doing. After her many mistakes, she blames the customer. Typical lazy government employees.


Most of the time they deliver mail unless it has snowed. My mail box is very accessible right next to the highway and we plow the area to insure delivery, but if the courier thinks there is to much snow even after we plow they won’t deliver the mail. It’d be nice if they weren’t so lazy and went the extra mile to get out of their vehicle and take a step or two to put the mail in the mail box. Maybe they should read their motto and take it to heart. “Neither snow nor rain nor heat or gloom of night stays these couriers from the swift completion of their appointed rounds” except in Lyons Colorado then they only deliver when it convenient for the courier.
