I got injured at the drive up bank window. My last duty of the day as general manager was to make the daily bank deposits on my way home. This day I had to buy 400.00 worth of rolled coin for the business. At the drive up window I had to pull a 40-60lb bag of coin from the teller window and twist and put the bag on the passenger seat of my car. I herniated a disc with this twisting and pulling of the coin bag.
