I've been retired for the past three years, and happily so. Before that I worked in the accounting office of a Walmart. My job was to count and process the cash from the previous days sales. My favorite part was processing the coins because I usually brought home silver coins every day. The processing machine would kick out the silver and the manager would come in and oversee an exchange for face value.
Paper bills were counted, sorted and prepared for deposit to the bank. I ordered cash from the bank when we needed an influx. There were tons of reports to prepare and it was a full time 5 day/week job.
One day, the manager came in and said a machine was replacing me along with the other girl that worked in that position. That machine did everything but kick out the silver. After the kinks got worked out of the cash machine, we were officially replaced.
